this is starting to get really frusterating..
ok so i know this problem doesn't have anything to do with my TUNE (enthalpy 480cc injectors and z32 maf)
anyways i hooked up my new o2 sensor today thinking it would fix my rich idle problem, but NOPE didn't do shit...
engine is redtop sr20det, with 264 toda racing cams and adjustable cam gears, i retarted the exhaust side 2 degrees, and the intake side 1 degree, so i could get the ignition timing at 17BTC, i had them both set to 0 degree's which is stock setting i believe, and could only get the timing to 14BTC.
anyways while cruising i get a solid wideband reading of 14.7-15, but when i WOT it goes to around 10-11 and it hesitates
the car reads high 10s and in the 11's during idle, i unplugged the maf while it was idling to see if anything would happen, but nope the wideband reading stayed the same.. so i plugged it back in, started the car.. turned it off and checked for codes, and got code 12.... so im like "oh shit i might be the maf causing all of this..." i come back 1 hour later to check again and it throws code 55??
im totally confused.. and im sure my maf is wired up correctly, it revs all the way up to redline no prob...
help me.. i've spent so much time and money on this fucking thing
ALSO when i cold start, it sounds like it misses, but when its warm it sounds normal, just really rich..
