CHEVY COBALT DEAD MISFIRE CHECK ENGINE LIGHT FLASHING DIAGNOSIS

Рет қаралды 37,829

Жыл бұрын

Welcome back! In today's video we take a look at a 2008 Chevrolet Cobalt with a 2.2l Ecotech engine. The customer complaint is that the check engine light is flashing and the engine has a severe misfire! After replacing the coils and spark plugs we realize that the misfire is more serious than we initially thought. Follow along as I show you how to diagnose an engine with low compression and how we were able to identify a leaking exhaust valve.

Eric, in my opinion, you are one of the two best diagnostic experts on automobiles that are on KZfaq. Every step of your diagnosis is to the point with important information and without a lot of filler (such as how to remove this bolt, or how to remove the spark plug, etc) Each step is quickly stated with all the important information. This coming from a technician that worked in dealerships for over 40 years. I thoroughly enjoy watching your videos and to try figuring out the problem along with you.

you could have put a rubber glove over exhaust and taped to seal. to demo the air leaking as it would blow up and explode and looking at the valve it was wobbling so the valve stem guide is shot can't wait to see fix keep up the good work Eric

It wouldn't be a bad idea to do a leakdown test on the fuel injectors. Sometimes a partially plugged one can overheat the exhaust valve and burn a chunk out of it. I realize this one appears to be bent or the seat in the head is fubared, but just saying.

@abdul-kabiralegbe5660 Жыл бұрын

The part 2 should be interesting: finding out why the valve travel seems shorter (not seating) or appears bent.

Well I think once you take care of the engine issues... there may be a good possibility that the transmission issues could correct. Erratic Rpm can disrupt inputs, and include flag false codes. I'm looking forward to seeing the work getting done! On another note.... other YTers and colleagues and I just got done with the Super Saturday Automotive Training event here in Philly. You NEED to go to one of these events... and Oz I'm sure would be there too.... though he wasn't at this SS, I think he was just at ASTE in NC. You would fit right in! Plus! There's so much knowledge being passed around! Stay safe! Ttys

Fixing the engine will not fix the shift solenoid concern on this. This is a 4T45E trans and that code P0973 is a 1-2 shift solenoid circuit code. Have put lots of solenoids in these for that, also wire damage on top of the trans for different circuit codes, especially rodent damage.
