In an effort to salvage a video I came out with this one. I have been messing with a screen recorder on my Autel 908 and it really messed up on the first vid to the point it just wasn't usable. Needless to say I drag you along for "Part 2" and try to salvage what I can. Oh well, some days you get the bear and some day the bear gets you. -Enjoy!

This is a method I learned from him and has been very helpful and can be added to your diagnostic arsenal as well!

@deathk26 4 года назад

I recently had a sudden dead cylinder misfire issue with my '06 G6 V6. Got a P0303 (cylinder 3 misfire) along with the flashing CEL and lean codes. Went through troubleshooting steps: swapped plugs and wires between cylinders, checked spark with inline tester, checked compression on that cylinder (was 190-200PSI). Was looking like a fuel delivery issue. Tested the injector coil resistance and it was good. Checked as much wiring as I could and nothing seemed amiss. Checked the signal from the ECM to the injector and it looked good. All evidence was pointing to a clogged or stuck closed injector. I replaced the faulty injector (new bottom o-rings for all the others too) along with plugs and wires for good measure. Was a bit of a job due to having to remove the top intake plenum and everything in the way. Got it all buttoned back up and that fixed it :)

Hi Eric, After the injector swap and you fired the engine and reviewed the scanner info, you mentioned the slightly negative fuel trim averages and theorized that vapor pulled into the pvc system from fuel contaminated oil was likely he reason. Brilliant. Information like that is another reason as to why I follow your channel. Thanks for taking the time and effort to share your vast depth of knowledge. I began my learning 60 years ago in the pages of my beloved HotRod magazine.

Spits and sputters. Drives ok for a minute and backfires and pops the next. Had a few local guys try to diagnose the issue and it still hasn't been diagnosed. Has random misfire code. Has codes for running rich and codes for running lean. Just frustrating to keep spending money for people to not figure out this issue. And I have a beautiful truck sitting in the garage that I can't even drive. Once again. Awesome job the people in your area hopefully realize how nice it is to have you for such issue.

@spelunkerd 4 года назад

Gotta like the way the scope recorded the results, at about 6:21, and it was helpful to see how you had the pressure sensor attached later. Of course the slight variance in the pause between each test doesn't make any difference, since the duration of each 'on' time was identical. Cool to see the test automatically boosted rail pressure to exact baseline before each cylinder test. Excellent point about how excessive fuel in one cylinder causes lean misfires on the rest of the bank. It is so nice to see another SMA video!

@JoesAutoElectric 4 года назад

So crazy other mechanics don’t use the tools you do to diagnose issues, I took one automotive class in college and learned how to diagnose issues like this with an o scope. My open lab teacher also told me to “not dry hump my injectors”. People who don’t know how to diagnose things end up throwing parts at it, “why don’t you change them all” ? Sometimes it’s not worth it sometimes it is, sometimes - if ain’t broke don’t fix it! Anyways love your vids always reminds me of the valuable stuff I learned from my teachers and myself from working on my own cars!

Great video Eric. I solved my OSHA approved bucket issue by taking 36 inches of 3/8 rubber fuel line hose, splitting one wall lengthwise and securing it to the rim with goop. Wait 24 hours and then no more slipping. Plan B is to purchase a work platform (about 12 x 30 inches) with rubber tipped legs made by Werner (not a sponser). These are available at Lowes or Home Depot and often on sale 3-4 times during the year.

@dandearman2871 4 года назад

Thank you for making these videos and I always learn something new when I watch. I bought a scan tool that I can plug in and look at a few things and your videos help me understand what I am seeing like the fuel trim and other things, what is normal and what isn't. I just bought a used 2018 GMC Sierra so another reason to watch. Days after I bought it the fuel pump died and they replaced it under warranty. The truck was acting up when I took it in and when they did a test drive it completely died on them and they had to have it towed back to the garage.

The speed of that Pico injector test is awesome! I have done the injector test manually a few times with the OTC controller and a pressure gauge. Each time I had to do the entire test twice, on eight cylinders, to confirm my numbers and even then I was not 100% sure it was right.

Interesting that you should post this. I just had an 06 2500 w a 5.3 that had been to 3 shops for a rich code that they couldn't figure out. They replaced o2s, pump, MAF, and oddly enough, intake o rings. Shop before them did coils on bank 2 and full ignition tune up. The 3rd was talking about a new ecm. When I got it, every cyl. on bank 2 showed misfires in history, but only 8 was current. I used my old school Snapper fuel pressure gauge with the scan tool hooked up and ran the balance test. #8 showed a 12 psi difference as opposed to the rest. Honestly, I'd not seen this style injector fail like this before, so your vid is definitely worth watching!

Most of the time, it's usually specified to use clean engine oil.

@davidquinn6161 4 года назад

When you mentioned "oil" to lube the "O" rings, I assume you didn't really mean engine oil. But just for the record, never use engine oil ( or petroleum based greases) to lube "O" rings. These will destroy the "O" rings. Only use silicone based lubes. As Eric mentioned, dielectric grease or brake grease are good. I buy "O" ring grease at my local swimming pool dealer and use it for this purpose.

I clear the codes run it for a week then the money light comes back on with the same old 304 on the number 4 cylinder on the v six 2006 jeep liberty. I am now considering the lifter to possible be bad causing a slow release of exhaust or not closing all the way in turn making it idle just a little ruff on that cylinder. some times the money light will go off for a week or two and then randomly come back on with the code of 304 on #4.

I have a 99 w/ a 6.0 that does this from time to time. Only difference being that the misfire is pretty faint and the pcm does not detect the misfires...they are prominent at idle and seem to go away under throttle. I typically take them out and throw them in the ultrasonic cleaner and run some injector cleaner thru them using a 12v power supply. Good diag E...keep em comin.

You were correct on the injector clip it is designed to stay on the injector during installation and its keep it from being dropped and lost another great video very entertaining keep up the great work
