Did you see a spark at 4:30 ?
@@frank700se I did see a glare of light, not sure if it was spark
do you know the best spark plugs for a 1999 vw jetta mk4 4 cil?
@@keelyaguilar8102 Here are the part numbers that recommended for that engine Part #: 101000062AB or 101-000-062-AB
What do u do with extra coolant left in funnel when the bleeding is done? Also do you just leave the system fully filled with coolant like that? Its above max on the radiator...
@@jogalong usually you put the extra on the reserve tank. Normally if you let the engine cool down, the level should go a slightly down on the radiator.
My short term zero % and long term 27%, but long term not go under 18% whatever RPM, if RPM like 3000 or more long term be 18%, you know if the vacuum leak or something else ?
@@chrisisho2557 Seems like a vacuum leak issue. Does your engine have MAF sensor?
Worst video I’ve ever seen on this subject, my god.
also typical problem with these wires . the wire's insulation at the tip fail and power is grounded to the metal cover before it reaches the spark plug .
Hi Eli, do you recommend going to iridium plugs on a 2015 VW Jetta 2.0L gas sohc.? I was having engine misfire & flashing check engine light sometimes when I was driving and accelerating, so I replaced my spark plugs, spark plug wires and ignition coil as well. Instead of putting in Bosch FR7HE02 which I saw in couple of youtube videos and which are Nickel plugs, I put in NGK ZFR6FIX-11 which are Iridium plugs, Also I replaced the wires with Denso Ignition wire set and Ignition Coil with NGK Ignition Coil. I don't have engine misfire or flashing check engine light anymore but I can hear like a sparking sound after some time when the engine starts. Do you know where I went wrong? Also could you please tell the name & model of the OBD scanner that you used in the video. Thank you
Yes, only if the original spark plugs from manufacturer are Iridium. Sometimes the heat range of Iridium plugs can run too hot.

It would be nice if you had capable scanner that can read misfire counts to make sure your replacement parts was a fix.
Of course you can't diagnose w/o looking @ a vehicle, but let me ask you this... Any clue what a $500 repair may be if done by a mechanic "on the side" & not thru a brick & mortar shop? I've got s/one wanting to charge me that amount, but won't share what the issue is unless I pay the *$$$* for his diagnostic scan. In o/words, I can pay him for the scan results...he shares what the problem is, & I can choose to have him do the repair, or I could shop around & have s/one else do the job. Not knowing what the problem is, I DO know he's reasonable, & he's good, so that price of a $500 repair I'm sure would be less than any shop, but does knowing that he would charge $500 for the repair give you ANY clue what may be the issue? I've replaced the MAF & the two air filters, but I don't think that has resolved the issue. Both Advance Auto & O'Reilly's scanned & said it was the MAF. The codes (two of them) wer P0174 & P0171, with "Fule system 2/1 lean & mixture is too lean.
It's hard to say, but since it's affecting both banks, it looks like you have some sort of vacuum leak. It can be your intake manifold gaskets or most notorious problem for these engines is the intake runner system going bad and creating a vacuum leak.
@@EliTheOBDTech Does his labor charge of $500 tip you off to one being more likely than the other? Thx!
@@Kman. To do either job, the intake plenum must come off.
What if that pump is actually bad
@@EliTheOBDTech I’m experiencing that 411 code but I don’t wanna have to take the motor apart if I don’t have too
@@Mitchyymitchmobile p0411 is not a fuel pump issue.
Sorry, I misread your comment.
@@EliTheOBDTech yea I know I never mentioned fuel, I was talking about the secondary pump
@@Mitchyymitchmobile You might have a restricted carbon contaminated secondary air pump that's causing your code. Worst case scenario, the pump is faulty.
Is it possible to preform the test using thindiage operating on diagezone pro v2
I'm not familiar with that device.
I know this was awhile ago, but did you have any codes come up when this "no start" happened?
No codes were triggered.
Got a 07 Escalade been having HELL with this car and o think you just saved me!! Had the same issue in the same spot!! Day 1 I’ll keep you updated
Sounds good.
If there is a vacuum leak would that be causing a significant loss in power?
Your MPGs will be affected. Depending on how big of vacuum leak you have. The MAF sensor will not be reporting properly, due to unmetered air.
Great video! Mine has rough acceleration coming from an idle stop at a light (also sometimes engine stalls coming to a stop). It smokes iddling, stutters taking off til some point. At regular speed on the highway gives no problems Changed 2 coils, 1 injector, spark plugs, air filter, fuel pump & fuel filter are fine, oxygen sensor. Keeps giving p300 code
It could be many things. You may have a MAF sensor that can be contaminated causing these performance issues. Sometimes, if you have oil pressure problems it can affect your VVT system, such as your variable valve timing solenoid, VTC Actuator and that can cause p0300. Worse case scenario, a head gasket issue can also p0300. If you have ascan tool look at your fuel trims and see what the pcm is doing. Keep me posted.
@@EliTheOBDTechOk!! Thank you! I'm going to check that. I'll let you know
You made it so easy!!!! Very helpful. Thank you. New subscriber!
Thank you!
That valve (or whatever it's called) on the canister has an o-ring and there's also a plastic tab which comes off of the valve (opposite of the angle of the camera) which holds the valve in place with a screw securing the tab of the valve to the canister itself. After inspecting the o-ring to make sure it's not torn or otherwise compromised, fully seat the valve into the canister and make sure that screw is snug against the tab (or little arm which comes off of it) and screwed snugly into the canister.
Did it throw a Check Engine Light Code? If so, what was the trouble code?
No trouble code
Hey bro do you have a video of how to do the bypass option if that is what the customer is opting for??
kzread.info/dash/bejne/mZh6rNqghdq3Xc4.htmlsi=N6Xl_iYsQY8fBitr
The test failed for the 2009 Tahoe. What is the problem?
You need to meet certain parameters for the relearn to happen. The scanner should tell you the required procedures.
@@EliTheOBDTech The rpm reaches 4, 5, and also the last, but the test fails،Tried more than once but failed
@@user-jp2lm5jz1q Do you have any codes stored?
@@EliTheOBDTech yes
@@user-jp2lm5jz1q I not 100% sure, but the code(s) may be the reason why it fails. Are you able to erase codes? If yes, clear and then retry.
Do you know what it could be when my Volkswagen starts shaking because of the engine , like should I just get rid of it then because I don’t know how to fix cars :(
It could be many things that can caused engine performance issues such as misfires due to bad ignition coils, plug wires, spark plugs, faulty injectors, faulty intake manifold gasket and worst case scenario mechanical problems such as low compression or faulty head gasket. Other possibilities would be jumped timing chain, faulty VVT control solenoid, cam sensor, crank sensor and faulty MAF sensor.
Best thing is to have your vehicle checked out by a professional. If not, get your vehicle scanned by Autozone and have them print you a copy of all codes stored, if any are present.
@@EliTheOBDTech thank you I got P0300 random/multiple cylinder misfire detected and p0302 Cyl2 misfire P0301 Cyl 1 misfire and P0304 Cyl4 misfire and P0351 ignition coil A primary/secondary circuit and P050B cold start ignition timing and P130A hide cylinder, do you think it’s worth fixing up? Because I feel like the misfires are expensive and I don’t know what to do or if I should just sell it for scraps
@@Iebaxos It's hard to say, you need to find the source of the problem first, to determine if it's worth fixing. You may have a jumped timing chain causing these codes or a faulty ignition coil module.
Seriously, this is exactly what my vehicle did two days ago. THANK YOU. The codes, the vibration, the light on the dash. Identical. You saved me so much grief and money.
so what caused the low compression ? was it a intake gasket leak or a piston issue ?
It was actually a bad lifter
Good video I only put the fuse on the Blue cable to the green Cable
What type of handheld device/ devices do you use?
I use many types of device brands. From Launch, Autel, Bosch, OTC, Mac, Matco, Autoboss, Injectronic and Snap-on.
What’s the difference between ignition coil and plug wire
Ignition coil is the unit that creates energy voltage spark to be delivered through the plug wires
Thank you for making this video! I found a frayed wire rubbing on my front differential (4wd) driveshaft under the drivers side door. I had code P0641, stabillatrak lights, also MAF and Crank Sensor codes. I believe the wire was running to the Fuel Tank Pressure sensor.
Glad to hear that this video was helpful.
What is the reason to unplug all sensors?
I’m chasing the 5v short 2009 Silverado 6.2, died last test drive when I turned
@@kevinhodges3374 To verify if it's a shorted sensor in that circuit or if it's a shorted 5v reference wire. The unplugging method should be done with a capable scanner that gives you the 5v reference data or you can use a volt meter connected to a 5v reference sensor signal for that circuit and watch your display to see if your voltage goes back up to 5v as you unplug each sensor one by one.
So if the short stays after unplugging the sensor than more than likely a wire is the problem.? Thank you
@@kevinhodges3374 Yes, that is correct
@@EliTheOBDTech how would I use the volt meter to find the shot in the 5v?
I have the code PO651. 🤔
You may have faulty sensor for circuit 2. Try disconnecting the connector to each of the 3 sensor for circuit 2 one by one. Crank position sensor, Throttle position sensor and Accelerator position sensor and see if your code goes away or if your 5V reference comes back to normal.
Great video! Never mentioned that hose part number. Still thank you 🎉🎉
Is there a way to bypass you think the regulator? Since you can’t purchase the regulator. Philips screws are sieved on the less. Thanks for the video.
I’ve changed spark plugs and the ignition coils and I’m still getting codes p300 and the p303 for my Sentra SER spec v 2006 idk what else To do
Check compression, you may have a mechanical problem, such as low compression.
@@EliTheOBDTech okay will do thx
Just replaced the sensor, how do I clear the code ro pass inspection? The code is still in the computer. thanx!
By using a scantool or removing the battery negative for atleast 10 mins
If the code can't get cleared, then your problem is still active. You may have a wiring issue.
@@EliTheOBDTech Thank you for responding! It’s the 2000 year model XE, I think the wiring is bad, but i’m gonna disconnect the battery for 10 minutes. If you were in fort worth, I’d pay you to fix it, lol!
@@justchris846 Yes, distance is always a big factor, lol
Thanks for this information. My issue with a Mazda 3 2012 its similar. The SHRTFT1 is aorund 0 to -1≈-4, normal, but the LONGFT is around +9 to +14 in idle. When i drive the car this drop to +3≈+4 and the scanner some times go to check engine with the P0171 code. My fuel consuption is OK buth the power engine seems to be lower compared with before. Also sometimes the start goes difficult in the first athemp but goes normaly after the second one. This still could be a possible vacum leak or a fuel pump/inyection problem?
I would start with the MAF sensor being dirty, then potential vacuum leak.
Great info I appreciate it.
Thanks
Is it a crankcase breather hose ? . It doesn't look like one that's why I am asking.
It's a vacuum hose, but not sure to what component it connects to.
@@EliTheOBDTech when you google m271 engine vacuum hose- a breather hose pops up. Is it the one which is located underneath the air box and to remove the two parts of it including the valve you need to loosen up the compressor? ( The upper hose is fully exposed after removing the inlet manifold ? .
@@harnas3848 Yes, that is correct, the pcv valve lives in that area
Underneath the intake manifold and next to the super charger assembly unit.
haw to replace fuel volume regulator control circut /open?
Hey there, I haven't come across that scenario on a VW.
my alternator just died in my 03 solara 3.0 so i replaced it. car cranked but didn’t start so i got a new fuel pump same problem. just replaced main relay but still crank no start
You may have a faulty crank sensor
Clear as mud
Great job sir 😊
Touch it
I’m having same problem already changed fuel pump and no start just cranking
Have you tried partially pressing the gas pedal to see if it starts?
Was your cab smelling like fuel before you changed the part?
I have a problem that the scanner reported, but I see that the air doesn't work. code b2610-000 compartment dimming 1 circuit. I bought a 2012 Chevrolet traverse with a “new” sound and the original one came too, but this new radio doesn't work, could this code be because they removed the original radio and put in a newer, more up-to-date one? In addition to this code, there were others (BCM) u0184-00 lost communication with radio, (EBCM) system disabled information stored invalid serial data received
I’m getting p0641 and also a misfire. My oil pressure started to just not work. Would it be safe to say the sensor is bad and that’s what is causing these codes to turn up. It’s a suburban 2005
Most of the time its a shorted 5 volt reference wire that being shorted to ground. Yes, shorted oil pressure sensor can be the cause of the code and oil pressure gauge not working. Try following my steps from the video.
If you unplug the connector from the sensor and P0641 goes away, then your problem is the sensor.
Thanks I will try that. 🙏🙏
Que tal tengo un pt cruiser 2008 turbo me apareció el código P0522 y P0340 al mismo tiempo no tenía anteriormente códigos de falla y ahorita no enciende solo da marcha me no arranca ,sensor de posición de árbol de levas y sensor de presión de aceite tienen algo ver entre sí ? Porque tengo esos fallos que salieron juntos saludos
En estos vehiculos es muy comun que el camshaft position sensor falle y no encienda el motor. La primera solucion seria csmbiar el sensor.
Dealing with a 2008 bmw 328i p0171 and 174 bank 1&2 too lean. Smoked the whole car and nothing. +20 fuel trims drop closer to 0 upon raising rpms. Any ideas?
Was your smoke test done with a cold engine?
Have you checked your brake booster for internal or external leaks?
Not too familiar with BMW, but you may also have bad intake manifold gaskets that may not show up with a smoke test. Have you tried spraying brake cleaner around suspect areas for vacuum leaks?
Great content 💯 Thank you. keep it up brotha 💪
Thank you for your video it will help me basically to remove the solenoid cause it's better to check it visually an give me a better idea,.
Our ford escapes auto start stopped working and when we go to the settings the option isn't there. Do you have any idea why this would be the case
Hey bro, thank you for the videos on the hardbody. I haven’t found anyone who does detailed videos like you do. Keep making those detailed videos bro, beer on me if you’re ever in LA man. 🍻👊🏽
