my ka-t just recently started shooting me rich air fuel ratios during cruising on the high way and when i take off from a stop sign. my afr usually are 13.x on cruising.but know 9.x shows up on my guage. when i slam the gas the afr are ok...sounds confusing but idk how to explain it better...

your car sounds just like mine. i was checking my maf and everything. but i just found out my problem, check your distributor. the rotor of mine was ruined so it made my car run really rich. but that was my problem, hope that works

well i wouldnt have ever guessed but i checked under my distributor cap and my rotor was shot. and my friend told me that it would cause my car to run super rich. and it wouldnt idle well..but its runs fine
