Hmm...I have one question. Do anyone else here run lean when they start their car after its been sitting for a while. Thats whats my car does all the time, so I have to drive it for a little while and then thats when the A/F gauge starts to move. It also likes to disappear(spelling) past the red for a few seconds when I go into neutral, then it pops back up. Normal Or No?
(my car wouldn't be quick next spring, just quicker than it is now...haha)
Your car should run rich when first started "cold" and there should be little if any o2 activity for up to a few minutes after starting, since the ECU stays in open loop(no o2 feedback) until warmed up.Once warmed up the o2 feedback kicks in, in which case the A/F gauge will start jumping back and forth.
