Alright, so I have a 2000 alero 2dr. Its got the 3.4 V6 and its automatic. I don't know a heck of alot about this power plant, this is the first car iv ever owned and iv only had it for 2-3 months.
Anyways, my problem seems fairly simple but im not sure what i should check. The car starts fine and runs very smooth. But, once the engine warms up, it hunts when it is idling. (the engine RPM drops and then picks back up)
This only happins when it is warm and idling, not wile your driving.
I was thinking it could be a sensor...but im not sure what sencer to check, were that would be and how to check it.
Any ideas would be much apreasheated.
