[QUOTE="96gt02, post: 16159409, member: 169266"] Do all this on a cold vehicle..... Disconnect the negative battery cable, put a towel over the negative terminal on the battery to make sure the cable never touches it, run a jumper wire from the positive battery cable (still connected to the battery) to the negative cable (not connected to the battery) it may or may not spark when you connect them, either way its fine. Let it sit like this for about 10 mins or so as this is what drains all the capacitors and memory. Remove the jumper, reconnect the negative cable to the battery. Go inside the car, make sure all electronics are off, turn the key to on position for about 10 seconds, then start vehicle and let it idle. It needs to warm up from full cold to full hot, once it reaches full hot let it idle for another 5 mins then take it for a 10-15 drive, driving normally and you should be good go at that point. Definitely do the relearn before replacing the TPS, your suppose to do a relearn anytime you mess with the TB so the issue may have just been the motor and it hasn't relearned the new one yet. For whatever reason certain cars need the relearn more then others. [/QUOTE]
