Codes.....P0172 and P0175 I got a check engine light and pulled the codes immediately. I dont know what all to check, I've done a search and i checked everything I found regarding to these except fuel pressure(havent had the chance to do that at my shop yet and i dont have tools at my apartment). My MAF is a new stocker(about a month old,replaced my SLP MAF with it b/c everyone said it was a good idea) its just as clean as it was the day i installed it,no vacuum leaks,the car is idleing perfect and its running perfect, it had the plugs and wires done about 5k ago and i just pulled one last week to make sure everything looked good. Also has Bosch 13111 O2 sensors that are about 2 months old(header install) and i power flushed the fuel injectors about 2 months ago. I dont know what else I could check(other than fuel pressure which i'll check tomorrow) any other suggestions? Could it be in the tune, I have a mail order tune from diablo b/c i have more mods than the predator can really tune for and the car is running awesome so I'm kinda stunned by the CEL coming on. Thanks for all your help!
