Awesome video! Love watching the master of diagnostics at work! Thanks for once again taking us along.

I had it figured for going lean, but suspected an intake manifold leak on that right bank maybe... Good find, Ivan. Love watching you solve mysteries!

Dude thank you so much for this case study. I learned a lot. I’m going to try that on my Audi A6 2001 running rich at 25% with horrible stalling misfires. As a paramedic we have differential diagnoses based on vitals, signs, symptoms, ekg, tests. That is called internal medicine, diagnosing based on assessments, vitals, tests, signs and symptoms; to dig deep and finding the right diagnosis for a problem that is not outright obvious. You are doing the same but just in the car world. I applaud that you are acting like a true automotive technician.

Last winter my 02 Durango had a bad o2 the fuel trims went to 33 short and 33 long term so rich it stalled out flooding the plugs and did not set a o2 code or lean code . It set a p0129 baro code goes prove that you don't replace parts on code alone . Great vid :)

Excellent diagnosis and video as always, thanks for showing us

Good fix, what I kept going back to after you commented on vehicle having multiple converters, that vehicle warming up problem getting worse, thermal failure. What I really take away from this is the tools you must have to work on the modern vehicles, as opposed to the old ones that I still drive and am able to work on. Anyway good job!

Awesome, love your problem solving videos especially those where a pin in he connector is damaged/defective. Thanks

Love these case studies with the full size GMs :) Thanks Ivan.

Very cool . I had my share of ignition and o2 related cars this week , it can certainly be taxing ... but it's relaxing to sit back and watch you figure out yours ! Lol Great content as usual sir !

Finally, got some time to catch up on your videos. Well, done. From the beginning couple things came to mind such as clogged cat. timing, and O2. Do this next time. Go to oxygen data in the scan tool and look for current data pid and it would read 0ma compare to the other bank. This will definitely cut your diag time. Wait until you get 07 gm truck with same symptom and codes but it's a wild ride. Also, with buick enclaves. Good luck brother.

You are 100% correct about the test drive being critical. Sometimes what one person perceives as being the problem may be totally different from what the actual problem is. I've seen some techs that think a car has a transmission issue only to find a problem with the ignition system.

Yeah. You got me with that one Ivan. The fuel trims didn't seem to out of whack when you looked at them on the car park. Nothing beats a good test drive and fuel trims are king above all else really.

Like you said, the necessity of the test drive is crucial. One of your best friend very, nice job.

I want to go to Staten Island University! Nice detective work Ivan!!!! You're getting quite the reputation in State College !!!! I agree with the other gentleman in a previous comment. Why the heck will GM not flag a bad O2 sensor? Of course the ECM can detect exactly what's going on with this O2 sensor. Come on GM pull yourselves together and fix this problem !!!!! Nice work Ivan !

Great job Ivan.

You can command open loop with scan tool as another way to make ecm ignore o2 sensors. As always great to watch you go through your diagnosis

Blessings Dr Ivan..cheers🍸.

Ivan, Great job as always. I have a '04 5.3L that came from the factory with the wrong plug wires installed that developed similar random misfires. That engine comes with either Melco (Mitsubishi) square coil packs or the Delphi round design packs that use two different length wires. The Melco requires a 10.5 inch wire and the Delphi use a 9.2 inch wire. RockAuto lists both types of wires and packs if you want to see a picture. Anyway the shorter wires will reach the square packs but are stretched like a piano wire and begin to fail intermittently after time. Just something else to watch for. When in doubt, buy the longer ones. Looking forward to your next video.

Great video Ivan. That explains the intermittent long burn time 3ms and higher and the low burn line which happens on a rich mixture . Scope waveform was spot on! Reading the plug would have shown rich also but the waveform read it perfectly. Great call on the test drive nailed the O2 sensor. Check out the TSB 05-06-04-063 LM7, L59, or L33 Engines With Cold Start Rough or Inconsistent Idle, Misfire, MIL "On" or Flashing Requiring O2 Sensor Replacement & PCM Reprogramming... Again great video series Ivan!!

You are the TSB master, Bob. Thank you for looking that up! Yes, the scope was not lying. Now can you see the difference on the waveform between a rich mixture, and an actual misfire on a fouled plug? When I took the initial capture, the mixture was GOOD, but we still got the bad waveform, indicating the plug was already fouled on the previous run :)

Pine Hollow Auto Diagnostics Yep I learned how to read secondary patterns on a Sun scope at BOCES in NY in 73-74 and they are a great diagnostic tool but some inductive pickups don't give the details. I used to use my Snap-on scope but the Pico has such a better waveform. That waveform also look similar to a spark plug that was just starting to carbon track especially the way it dissipated the energy at the end and the long burn line. Rich fouled spark plugs waveforms look the same after 40+ years. Just think we were the ECM & O2 sensors back then & rejetted carbs, air bleeds, ign timing, changed spark plug heat ranges, etc nut now it's done in micro seconds. Reading spark plugs has become a lost art & the base of the plug is where the real reading is taken. If I can have easy access to a plug I yank it out and it tells a story and saves time sometimes. TSBs also have saved me from chasing my butt over an issue that is corrected by a software upgrade. Eric actually posted it before me I just piggybacked on his post. Your diagnostic skills are impressive Ivan...Look forward to your next video.

I agree. There are many ways to reach a diagnostic conclusion with computer controlled systems and you have shown that the most powerful tool for getting a clear graphical picture is a good scanner with scope. Its fun to watch how you walk us through the process and include the challenges you are facing along with the solutions. I watched your review on the LoadPro. Very understandable and you showed all angles, both the advantages and disadvantages. Every tool has its application. You will find the PP4 to have some cool features that help the technician save time in probing for voltage readings, continuity testing, resistance testing, and some other things. Where the Power Probe really shines is in its ability to activate certain electrical components with Power and Ground. Of course it can't be compared to applications where a scope and scanner are best suited. That is where watching you use those tools to find solutions is really interesting and fun. Keep going, I like to learn too.

Was it unnecessary to check the wiring to the O2 sensor, because the engine ran better with it unplugged?

Facinating

I would definitely be warning the customer that it's very likely a few codes and possible a clogged or melted Cat may be coming in the not so distant future as a result of running rich for any period of time instead of just bringing in to be fixed right away.

I'm far from being the expert here,but I did comment in the first video about the lean code... Out of that list of codes you had initially,the lean code would've been the first I'd attack with misfires. What was the reason the PCM set a lean code if the fuel trims were fine?

@PineHollowAutoDiagnostics

6 жыл бұрын

Yes Nick, you were spot on that the lean code was key! Apparently the failure only occurred once the vehicle is driven and the oxygen sensor gets really hot. Freeze frame data should have shown us this :)

Side Note: Did you know there is a hidden 500GB partition on the D10 that snap on doesnt use for anything. I have Mitchell and save my waveforms to it

My old '03 Saturn Ion had something similar - the O2 sensor would be fine shortly after you started it up, but after driving it a while so it got fully warmed up it would just pin itself lean and eventually started setting B1S1 low voltage codes. Could be GM got some bad O2 sensors around that time period that would crap out like this.

Cool, looks like it ran great after you unplugged the Oxygen sensor and ecu went to default strategy...under 100,000 ks not many ks for a v8..

The first video I thought the 02 sensor reading looked a little bit wonky.. Not a nice up down loop. But I disregarded it.. Because obviously it wouldn't be the 02.. That's the first part people throw at an engine when it starts misfiring.. I was surprised. Also if it was me I would like to test the heater circuit before throwing a sensor at it. Despite it not throwing a code for it.

It threw a B2S1 heater circuit code after I unplugged it, so heater was fine. I always thought people replace spark plugs, wires, and coils for misfire problems :)

I bet the plugs are fine... They're just flooded. Fix the O2 issue and the plugs will likely clean up fine.

I have the same problem but it runs better better when i unplug one of the bank 2 inyectors i plug it back i get back the misfire
