I was doing a Freind a favor .Doing brakes wheel bearing ect..... Test driving the car.It started Idleing high .This thing shoots right up to 2500 -3000 as soon as you start the car.Idle it does fluctuate sounds like someone is pressing the excelerator but mostly just arround 2-3 thousnd.

No check engine light .stuff a rag in throttle body and it comes down to about 1000 rpm.Checked for vacume leaks can't find any doesn't mean theres not one though.Any advise would be greatly apprecited.Thanks Philip
