I changed my MAF after these codes flashed, ran it for 10 min and it still runs like crap, kinda sounds like the catalytic converter is clogged. Could running the car this way mess up the cats? What other reasons besides MAF could flash 33&36 codes. I have a 88 iroc camaro 350 tpi, I've got the heads rebuilt recently, and it ran find until I took a 2hr trip and that's when code 36 flashed, when I drove back home and turned car off to unload stuff and turned it back on it sounded like a lifter got stuck, then gradualitly got lower but didn't go away till the next morning. I NEED HELP WITH THIS ISSUE, THIS IS THE ONLY CAR I HAVE NOW SINCE MY BRONCO BROKE DOWN. MY WIFE USUALY DRIVES THE CAMARO AND I THE BRONCO. ANY HELP WILL BE APPRECIATED. THANKS IN ADVANCE.

 

A code only indicates a problem with a system ;not that the item in that system is actually faulty
Could be wiring or grounds also
In your case you have the MAF burnoff relay code
