also what you can do to test your TPS sensor is, start the car, while running, unplug the TPS sensor, wait for the ECU to throw a code for it, or just wait 20 sec. turn the car off, plug it in, start it up and see if its stil giving you a check engine light. when you start it back up dont look at the ecu for codes look at the ceck engine, cuz the ecu wil store the code for a while. but you can clear the codes by dissconnecting the - battery wire, but its recomended you just, remove the fuse for your Flasher circuit, in your right hand shock tower fuse box (the main fuse box) for 20 sec. this way you dont ahve to reset your clock and radio.
