car was running fine a few days ago. I went to start it and it all of. sudden started running rough. checked and swapped the coils on the number five cylinder because it wasn't responding and it had oil on the stem. pulled the spark plug and switched it out, still same issue. coil #5 is still not responding all the others are. check engine light came on for ignition switch, maf and intake air temp sensor, and knock sensor. when I'm at a stop it idles and shakes like crazy. I jus cleaned the maf and throttle body a few days ago. I don't want to go buy a maf and the problem is still there.

 

that sensor would def be a culprit in my mind. replace it and the bad coil and see where you stand.

 

ok I just went to get the charging system checked out to rule that out, a buddy of mine has a spare mass air flow sensor so ill install it and see if that works, and try swiching coils on that cylinder.

 

I think I may have triggered the check engine light for the maf and iat sensor as I was cleaning the throttle body, drove around and forgot to plug them back in lol. car is still running like s###. I'm leaning toward the fuel injector on cylinder 5. coils are working, but the only thing is number 5 injector is under the intake manifold. smh.

 

think I solved my problem, badd gas!!! I filled up and put in some b-12 fuel and intake cleaner, and after driving around for a while she started driving normal again hopefully for a while lol!

 

did someone say fuel system cleaner??? Chevron techron is the best on the market. Works wonders man. Try it.

 

yeah man I remember someone saying to try fuel system cleaner earlier. I almost forgot about it.

 

Yeah you are back on the forums. Chevron representative...
