New Cobalt owner with CEL.
MAF goes .9XX lbs/min and misses then reads .6/7XXX doesn't misfire then reads .8/9XX and misfires again. Under light throttle at 2k rpms it's using 4 times the amount of fuel than at idle, I feel like that's wrong. Lol
Put a new MAF in and removed the one ACdelco coil and replaced with a duralast like the others and she runs like a champ. It was still missing bad with the MAF, and it still misses at idle :/. But WOT is all good!!
MAF fixed the fuel trims, now I read 1-2% for both LT and STFT.
