Is it currently a hard misfire and running rough at idle?

[@michaelszczys8316]

The way it sounds over the video i would be checking to see if there are any rods poking through the side.

[@bckr1532]

Nice informative video 👍 what scan tool are you using to get all that data?

[@SeeMooreVids]

Thanks. Good video..

I bought a 2002 envoy 2 years ago. Today I lost my 3rd coil. 3 since July last year.

Was hard for me to hear through the speaker but was there a buzzing sound as well as the taping sound? mine has one that comes and goes and is pretty much continues while driving wondering if I’m having the same problem

[@williamsteele9958]

Sounds almost like an old air compressor so thought maybe pcv but unplugged it and still got the noise

[@williamsteele9958]

Actually kinda sounds like an electric can opener

[@katrinalindahl1293]

How are these engines on these vehicles? I really would like to know I’m having a hard time trying to figure out some information about the engine. Can you help me out please

[@partsshooter]

They're good engines, just keep the oil change intervals tight, can't go wrong with 4-5k miles before changes

[@b2pcrew]

im having issues with mine, it keeps pushing white smoke out my exhaust if im at high speeds and makes a puttering noise and kinda misfires if that makes sense it has been working fine before i drove it a few hours on a trip

[@aidanmckinley8885]

check oil, seems like a blown head gasket

[@iwannabeastar2468]

Yep

[@philobetto5106]

yep that's the exact symptom

[@partsshooter]

Come because you WANT to... Not to support. Thanks

[@joemitchell9934]

I did all my coils and still get a blinking engine light and a code p0300

[@partsshooter]

Check for proper signal at coil and injectors. If you have mechanical noise, isolate causation, check valves and camshaft.

[@partsshooter]

Perform a compression test or leakdown test
