o2 sensor

 

which one??? the one on the header or the one behind teh catalatic converter???? and why does it do that, is it from the gas or they intend to go out like that???


THANX

 

uummmm... both? I'm not sure, but I know that the o2 sensor can make the car act that way. Are you getting a CEL? You can always check them both with a volt meter.

 

sry to ask. but whats the "CEL", and i do got a volt meter thingee!!!

 

Do not post such threads in the DIY section... MOVED

 

um...y?

i have the same exact problem. have since i bought it over a year ago. however waht he failed to mention is that it only happens when its cold outside. plus it goes away once the temperature gauge reads closer to normal idle temperature.


so it only happens to me when ive been driving around and had the heat on...then put it in park. it goes nuts

all i do is put the ac or cold on, or turn the heat off and the car warms back to normal idle temperature... and then it idles normally


i dont have a check engine light. never have, and ive had this same problem for the past year (only affects me in winter time)

any other ideas? i really wish i could permenatly fix it. it pisses me off

 

check your IACV and FITV

 

ok thanks. but what exactly does that mean?
