hey everyone, i've done some research and can't find a solution to my problem, here are a quick description of the car
90 JDM GT4
3 inch exhaust, no cat
replaced air box with cone
mines ecu
APEXI avcr
WTA top mount IC(from an RC)
the rest is pretty much stock
DIY catch can( using compressor filter)
so here is my problem, she is running very rich(aem wideband), at idle the gauge is reading 11.3-12.3
i recently changed my transmission, and when i was done with that the she was idling at 1100-1200, with the afr good, then a couple months later (cold weather arrived) and she started to run rich with the numbers above. i don't have an O2 sensor,there was none when i bought the car 3 years ago, and all was good until recently, she drives good, no hesitation, no power loss, no abnormal back fires, no abnormal smoke , no smells, nothing...only running too rich, i was maybe thinking the afm is going bad, but then again i'm not sure...any help would be much appreciated
if there is any info i did not put here just ask
thanks
