GM - Chevy Truck: Misfire Diagnosis

Just like skinning a cat there are many ways to get the job done. Being a professional shop I will typically use the tools I have at hand to diagnose in the most efficient way possible. However, in this video I use a combination of techniques to help us find the fault. Just remember, there is no wrong way of doing it if you end up with the correct answer. However, there is usually a more efficient way to do things. -Enjoy!

That injector could be perfectly fine, yet be clogged at the input or the nozzle with debris, and that could be why the scope looks the same. The flow test proved the diagnosis, and your methods work well even with this bizarre part failure. That is why you are the go to guy. I have an electronics repair background in schooling, but am an amateur car fixer and I love you videos. I always try to beat your diagnosis while watching, LOL. These videos are the best ones.

Hello P0300 my old friend. 2005 Chevy Express 4.8 with a random misfire. We replaced 8 plugs, all wires, #4 coil (dead); both sides upstream and downstream O2 sensors. Still a P0300 at freeway speed. The operative word is 'random'. Finally we replaced the crankshaft position sensor. Our Technician complained that the 'relearning procedure required accelerating the engine to 5,000 RPM: High 'pucker factor' on a 23 year old truck. My old friend P0300 went away. Now, a year later, my old friend is back. The only sensor that could add to the misfire condition is the camshaft position sensor. Since that requires R&R the intake manifold, and the oil pressure sensor is also located near the camshaft position sensor, we ordered one of them as well. Here is a valuable tip: On the camshaft position sensor, there is an 'O' ring at the very bottom. When that rubber 'O' ring dies, it allows motor oil to leak behind the engine into the bell housing frequently mis-diagnosed as a main seal failure. It can't be confirmed until the engine and transmission are torn apart revealing a main seal that is perfectly intact and the leak coming from a $30 sensor. (Ugh!)

It's probably not actually empty, the fuel senders on these trucks tend to do whatever they want, and usually that's show empty. They put three of them in my dad's while it was still under warranty, haven't bothered replacing it since.

The scope waveform demonstration is great! It really helps remind your viewers and myself that you have to look at a problem from as many angles as possible. Great video, good learning experience!

I always like to try and guess what's the source of the problem a few minutes into the video, and this one time I was right. It's amazing what diagnosing, trial and error can get you. And to find out coils, wires and spark plug didn't need replacing. Another great video, can wait to see what's next.

I swear, some of these folks who call themselves "mechanics" should really call themselves "parts cannon operators." Because that's all they know how to do -- fire a parts cannon at the problem in hopes that they get lucky and hit the right part. The thing I like most about this channel is the diagnostic procedures I learn. I have definitely learned a great deal about diagnosing issues since I discovered this channel. Thanks a bunch!!

I'm always amazed at how Eric solves the issues. First class mechanic/technician/electrician and all round guru. If I'm wrong tell me a better channel. There may be other good ones out there but Eric is top notch.

I agree there are several ways to process your diagnostics. But, in this case the old school method was the most precise. Great video, as usual.

This is a great, great example of thorough diagnostics, and why it's so incredibly important to follow thru every single path and theory. Had you scoped it in the beginning, and done no further with the injectors, it would not have been fixed. So many of us fall victim to this scenario. You just proved why it's imperative to be thorough and absolute with every method of diagnosis.
