This could be caused by many different things. You'll need to get it diagnosed to know what is causing the problem.

I have a 2000 GMC Sierra 1500 with intermittent high idle and had a diagnostics test performed. It showed nothing and was told process of elimination. Changed Idler Air Control Valve as recomended by machanic and that didn't fix the problem
