Fast Idle, drives without touching gas pedal
Re: Fast Idle, drives without touching gas pedal
I have a 2003 Pontiac Montana minivan, idles extremely high and accelerates without even touching gas pedal. HELP PLEASE. I've replaced the idle control switch, which I was told was the problem but found out it wasn't. Tia

First thing I would look at for high idle is a vacuum leak. Scanning the engine to look at the IAC (idle air control) and looking at the fuel trims to see if the computer is adding fuel or taking fuel away.
with a scanner you should be able to go ina and control the IAC and tell the idle to move up and down. That would tell you is your IAC was working with the computer commands.
