2004 Ford Escape Q&A
2004 Ford Escape Question: Very fast idle when in park- -when in gear vehicle goes 30-40 MPH on its own.
My problem is a very fast idle when in park and when in drive the vehicle goes 30-40 mph on its own. Also, the emission system warning light is on. I know nothing about a diagnostic code or where u find one. Man---when I looked under the hood I thought "Boy R U in trouble", this doesn't look anything like an engine I remember! - butcher
IDLE SPEED CONTROL SENSOR STUCK / OR A VACUM LEAK - Visitor
The only thing you can really do without test equipment is look for any loose or disconnected hoses. Vacuum leaks can cause this, as the previous answer stated. Also check the air tube from the air cleaner to the intake. Make sure it is secure and not cracked or damaged. Beyond that, you will need to have the codes retrieved to get more clues. Good luck.

I own a 2008 Ford Escape and was chasing my tail. Scanner pointed at Air Intake Control Motor (Sometimes referred to also as Idle Air Control Valve) which is a simple fix but part is pricy. I went to scrap yard and installed another AIC Motor and all symtoms still persisted. Idling high in park, accelerating to 35 miles per hour without touching the gas. RMP's would jump to 4000 RPM's in park and Neutral. Turns out that my cruise control line was seized up and a simple disconnection solved the problem. Repairing the Cruise will be costly but I can live without Just putting this out on this discussion board so that maybe even one person doesn't have to go through the frustration I did. - Jazz106
