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!

Like when I used to do winterizations on RVs, everyone had an opinion on the right way to do it. I would tell them that there are many right ways but there's only one wrong way to do a winterization. If the pipes freeze up, then that was the wrong way.

Simply he replied, check the ground by the left fender, sure enough one of the wires was crusted off, I crimped, started right up. I sent the head in for a valve job. It's still running till this day.

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!)

I work at a heavy fleet shop and we play swaptronics all the time. I love it because it removes all doubt. If you swap parts around without spending any money, why not at least give it a try?

When I was a crew chief in the AF, we had a radar issue we could not duplicate on the ground. Eventually we removed each component in the system, leaving only the wiring harness. Then each component was placed on seven different aircraft, with plenty of documentation. Then it is just a matter of time to see which aircraft picked up the original issue.

The way injectors are set up nowadays to make it real hard to bench test and injector in other words pull it out and check the spray pattern they do that for safety reasons so people don't burn up their cars because they don't have enough sense that you don't spray fuel on Sparks and on the motor not good combination I know I burned a truck up and put the fire out and rewired it and drove to work the next day or the day after I should say it's amazing what you can do when you got to get to work to pay for parts for your truck have a great day

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.

This is probably one of the most educational channels for new / experienced (and weekend warriors) mechanics out there. Not only is this informative for all of us, but it also has humor to it; it's hard to pull off sounding 'natural' when working on a vehicle... you're naturally gifted at being 'real', and that's rare these days -- wish it wasn't like that but unfortunately it's the world we live in. I watch all the videos for not only the comedic esthetic, but for the wide range of problems and different solutions to them. Everyone here is right, you really should teach; you definitely have the patience for it and you'd succeed due to the fact that you go about it in a real and entertaining way. Wish your shop was in Texas; with all the shops around here that try and rip people off as much as they can, you'd be a state favorite for sure.

I was raised on a dairy farm in Mississippi and am mechanically inclined but lack the skills and know how for modern vehicles. You are a blessing and I appreciate you and look forward to each née video. I really enjoy your channel, Watch Wes Work, and Pine Hollow Diagnostics. You guys are the best. You might be the best Kilmer impersonator I have seen lol.

In all honesty we don't know that the bad injector was the ONLY problem. We just know it was the one they couldn't find. There could have been multiple problems, and those are the cases that are a real pain to diagnose. (Now, they probably replaced a bunch more than they needed to. But maybe they didn't do _everything_ wrong.)
