Ok, so I just bought this car and a day later its having issues, like wtf but anyway. Well ok, so sometimes when I start it it will idle up to 2000 rpm's but in a matter of about a minute it goes to normal. Other times after its been driving for awhile and I come to a complete stop, it starts surging, itll go down to like 200 rpms and surge up to 1000. Earlier today at the gas station I filled it up and then the car wouldnt Idle at all, Finally after I let it sit for about a minute or so it started up and idle but was surging.

Any Ideas?
I appreciate any help you can give

Thanks
~Alan

I agree with the IAC becuase if it were an intake concern and/or intake gasket concern the problem will be present and constant at all times.


All IAC's are generic in operation and suspect to a lot of carbon. Sometimes they stick and other times they don't. You computer is trying to adjust idle but the IAC is not responding correctly.


However, here is a simple test... Unplug the IAC. If your vehicle won't idle, just apply more right-foot. If the high idel never returns unles by a fat right-foot then the concern is the IAC.
