when i am starting my car, my autometer AFR gauge shows 2 LEDs on the lean side (not sure if that is an accurate or valid point of reference, but it is all i have). will this harm anything? how would i remedy any possible problems?

ignor any readings you get for the first 5 mins or so. the o2 only works when it's warm.

after the car idles for a few minutes what does it read?? your O2 sensor has to warm up first to be accurate.

Don't even bother looking at your A/F gauge until you've been driving for at least 3-4 minutes. It takes that long for the O2 sensor to reach its operating temperature; until then its readings are meaningless.

it doesn't stay lit. it only come on when i start the car and during idle. after that, it goes off. what coudl cause THIS? because it seems i need the gauge to further diagnoze the previous problem

Funklord

its supposed to be lean at idle. you should only be rich at WOT

Are you still talking about when the engine's cold? You've had that answer three times...

i am saying that the gauge is only lit WHILE the engine is cold. and when i asked what could caUSE IT, I WAS ASKING IF THERE WAS ANY WAY TAHT THE WIRING COULD BE WRONG. the gauge is useless if it only comes on during the warming up
