I started my car this morning to let it warm up like 10min,and went to go back out to get in to go to work it was reving up and down from 6oo rpm tp like 1300rpm back and forth what is that? i hit the gas and it stopped.whats get ready to go on me? thanks alot.

 

Does it run ok? Kind of sounds like the Idle Air Control (IAC) valve is sticking, so it can't properly throttle. Does it only quit that when your foot is on the gas?

 

yeah it runs good and when i give it gas it stops and another thing when i first start the car it makes a gargling sound till it warms up but it goes away and that sound comes from the throttle area it very loud when i take the air cleaner lid off?

 

sounds like IAC. first of all make sure ur iac plug is properly plugged in

 

it is, it dont do it all the time and it was a real cold thatmorning if that helps?
