Also could be iac hanging up or possibly bad tps sensor causing high idle. Had that before. Thought throttle was sticking.
Also check cruise control pod sticking?

If base idle isn't adjusted properly throttle plates can stick. In other words throttle is closed too much causing plates to stick in the bore. Disconnect throttle cable to isolate it from the TBI unit. Check if it still sticks.
