Because you need to replace the sensor?

oh, the sensor tells teh comp. how far the throttle is open, and if its bad it may think it has more or less opening than it does.

TPS is bad. That is how you test it. When you unplug it, and it runs better, the TPS is bad. The engine is not running as good as it can w/ a good TPS (when it is unplugged).
