MY DENALI START ACCELERATING AFTER YOU HAVE REMOVED YOU FOOT FROM THE PEDAL.

1999 GMC Yukon • 113,000 miles

About 2 weeks ago my car started to accelerate when you remove your foot from the gas pedal. What can cause this?

Could be a fly by wire issue or a vacuum leak that has raised the idle up. You need to get it checked to verify and get a bid.
