Engine Performance problem
2000 Chevy Impala 6 cyl Automatic 135600 miles

It started as an intermitted thing but now its consistent. The car will not idle down! I would get up to 50 mph or so and when I slow down the engine will continue to idle up as if i am pressing the gas. When I stop its still idling up. Any suggestions? Thanks

sounds like your problem is the tps(throttle position sensor). I would have it checked asap and replaced if necessary.
