just wants to start by saying car before this season had no issue with airfuel it ran richer when on the throttle full and ran about 14.7 on idle or consistent throttle while driving i installed fmic,screamer pipe, catch can. pullies, thermal intake gasket. i had installed isis intake manifold fold but went back to stock for reason that arent very important but after doing soo my fuel pump did not get power ive checked relays under hood closest to batttery and fuse inside on left kick panel. regardlesss to say i hardwired my fuel pump and that was fine. but not my issue is when when im driving its having all these issues with running rich when i left of the gas and im hitting no lower then 12.3 on airfuel when full throttle and full boost(15 psi T25) sorry dont know if i mention its an s13 with sr20det. also for some reason my o2 sensors keep getting carboned up then the air fuel gets worse and having rpm spiking at idle. , change o2 do a diff one n then works fine at idle. someone please help its driving me crazy that i cant figure it out and no ones really wrote about this issue that i can find.
