My miss fire just started and is sporadic. P0204 jeep liberty. At times I turn on the vehicle it acts normal and other times on start is misfires cylinder 4. I swapped the coils and spark plugs to see if it would follow and it doesn't. Now I believe it comes down to the injector acting sporadic or from the the electrical plug. Any thoughts?

Thanks for the bonus footage! I thought you were gonna leave us hanging. It would've been like watching a movie and not showing us the ending.

My Jeep is a "crank, no start" and I needed a refresher on how to use a Noid light. I learned more than I was looking for by watching this video. Thanks Dave.

Excellent Video, your ability to make things easy to understand for an amateur mechanic is unmatched. Please keep them coming!!

I've looked at a lot of videos about misfire diagnosis and using the Power Probe and this is by far the best that I've seen. Clear, simple instructions. You've taken out some of the mystery and confusion that others gave.

I'm not sure why it took me so long to find your channel, you earned a sub today for sure. We have many similarities, not least of which is our addiction to quality automotive tools. What I really like about your channel is the way you explain how these systems work first, which gives a reliable compass to look for solutions. It was fun to see you use PP4 for the fuel injector. Eric O sent me one of those but I've never used the fuel injector feature. Once I see the test light flashing, I tend to follow the ScannerDanner blueprint of looking at current waveforms. There are lots of right ways to get to the answer.

Enjoyed the video. Really glad you showed the bonus showing the problem. Thank you for doing the video.

@@BigDog50001 will not the reverse voltage spike flows back to the power feed side and cause short circuit?? Analogy to a diode in a relay, is similar diode or capacitor necessary to absorb the reverse spike and protect the circuit and the solenoid itself?? Please kindly elaborate a bit more.

Great video and information. You got me towards the end. I was thinking dude what do you check next if the darn injector is getting power and fuel. Then right before I was about to type you the ?, you jumped in with the bonus video of checking the compression and leak down. After that I was saying out loud in my garage to the point my neighbor looked over as I was yelling this guy is awesome and very knowledgeable and lest us lay people know each step to achieve results. I am working on a 2012 dodge caravan with the 3.6 pentastar engine but it looks like your steps will work. I replaced a ton of stuff that requires relearn but I can’t get the van to barely run. I don’t think bank 2 cylinders are firing. I am going to start at your step 1. Thank you Sir for helping out us little people who can’t afford to send the vehicle to a shop.

Allan Stein Thank you.

Thank you for the video. I am trying to diagnose a Misfire cylinder 1 P301 hyundai v6. I am at the fuel diagnosis stage. My suspicion is not ignition (spark) based on maintenance and tests of ignition. Timing seems not an issue as cylinder specific on this DOHC timing would cause entire bank issues (misfires P300). Assuming that not seeing the pintile spray pattern through these tests is an issue however your stating that the Power probe 4 showing more data compared to a known good injector shows simpler pulse pattern thus not injector issue.

Thank You.

Great video, thank you. My 1994 Dodge Dakota 5.2 is driving and running, but throwing an intermittent code for the injector output signal circuit. Even when running fine, I get power (test light bright on all injectors power side), but no ground (no pulsating light to ground side on any injector). Do you know what may cause this... And how is the truck running with no ground to the injectors??

thanks

I bought one like this but there is no injector mode but how can i test continuety if the harness of ecu inside the car and the injector outside and ive tried noid tester no pulse and i have no start issue want to check continuety so can you help with this power probe ,how can i do the test?

I have a issue on injector number 4 on the 1996 Toyota corolla pulsing light but then it goes solid signal I have put a ecu which is been repaired but now with that issue it causing to much fuel coming out in cylinder number 4 causing it to flood in fuel and getting white smoke with strong fuel smell not sure if it's the ecu become faulty again less than 16 days of replacement when the pulsing issue started I change spark plugs wires relays fuse and spark plus distributor n only get a p0304 cause but the irregular pulsing to just the light injector test staying on any ideas what it could cause for I injector 4 to stay on constant. Sorry for my explanation with my grammar.

Thank you for Brilliant video, one question please, can I carry out same test using power probe 4 for testing Diesel injector?
