The throttle position sensor is located on the throttle body. It should be tested. If it fails, replace it; they are only about $40. A new one would require ADJUSTMENT as well.
Would be a good idea for you to buy a repair manual for this procedure, and for future repairs. Best money you can spend. Factory service manuals are best, then Chiltons. Haynes are the bottom of the totem pole for manuals.
