My vote is for the return spring on the backside of the TPS being gummed up. I live on a private dirt/gravel road and every summer I have to pull the TPS and clean all the grime and dust out that gums it up. Sluggish spring will be obvious once you get the TPS off and work it with your hand. (that sounds terrible!! <img src="/forums/images/graemlins/ignore.gif" alt="" />) Go easy with any cleaner you hit it with. I usually give a short spray of electical cleaner or NC brake parts cleaner while holding the TPS springside down. Spray, work it, spray then let dry or blow with compressed air. <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> Anyways, works for me!
