what is wrong?
my sister has a 99 lumina with the 3.1 engine. when you first start the car you have to keep your foot on the gas and double foot it to drive it. but once its warmed up it runs fine. just replaced the alternator and battery cause they ended up goin out, don't know if that has anything to do with it.

so the intake air temp sensor?
hoity---eight bucks online.....aren't you glad the judge is helpin' you today?~
yes the AIT sensor...don't tell me you replaced it already?
or "air charge" either works on a microscopic level....most annoying~
no I haven't, but why would it make that big of a difference
what this thing does is check the density of the air comin' in...when the engine warms up, it makes the mix lean...when it's cold outside it chokes it down...I don't remember if you can remember back in the old days there was a heat riser...B9 control robot arm up to the snorkel where there was a diverter that would take raw outside air in or from the heat-riser...then would pass it onto a spring "butterfly valve" and a two position idle that'd kick down to normal idle at operating temp....don't you remember those things?...well this little goodie thanks to our new technology (of 15 years ago) lays to waste all this extra hardware....am I makin; sense now?~
