I'm a firm believer that it doesn't. REGARDLESS though....a bad TPS is a BAD TPS. SO like stated before....dead spots or spikes in the sweep of the throttle indicates a bad tps and it should be changed. I'm a FIRM believer that the TPS should be ideally at .99v and close to 5v at WOT. As for the guy that said his car shifted funny with it unhooked....thats b/c the ECU no longer knows how far your foot is on the pedal...if it doesn't know, it can't compensate. A hanging idle can be caused by a improperly set TPS, faulty TPS, or a faulty/dirty Idle Air Control Valve among other things but those are the biggest offenders.</blockquote>
