i cant seem to figure out whats wrong with my car...why does my idle go really low like 500...really low but then it only happens when the car reach the right temp and stopping on the traffic light...thanks much

 

You probably have to do a simple idle adjustment. If it does this especially with the headlights one then pop the hood, look for a small set screw on throttle body, use flat head screw driver and adjust the idle to 700-800 RPMs at normal operating temp. Try that it should be better.

 

This may sound a little wierd but one time when my radiator was low on fluid i had this problem with my idle but it kinda went away when the car was warmed up, kinda off but wanted to see if i could help.

 

yeah, i'm kinda getting the same problems as you, but my check engine light comes on, =*\... my da is saddening me... what's wrong with my car??? help mee!!

 

i will try that turning the screw on throttle body...and if not then i will get my iac valve clean out...hope this will do some changes...
