My 1999 GMC Yukon Denali start accelerating after you have removed you foot from the pedal.
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.
