Hi all,
I just wondered what kind of AFR's you would expect to see on idle on both hot and cold engines.
The warmer the car is I can see AFR's creeping up slowly from 14.5 normally fluctuating to 15.2 but on some occassions it seems to get to 18s at which point the car is hunting and has uneven idle. Seems to suggest possible air leak maybe... but I am also pulling the dreaded TPS 41 code too (I think thats open circuit).
I have spoken to a couple of other members and it seems others have seen similar, encompassing issues with o2 sensors TPS, Idle stepper motor and possible leaks...
I also wondered if there were any guides on setting up TPS..
Cheers
