do you have it setup right or not? that is the first place to start. Then test your TPS with a volt meter. Then search about the S-AFC learning.

TPS. also i have never been able to get my TPS to read down to factory specs (.6-.9 kohms) for the widerange. i cant get it below 1.27.... how the hell do i get it down under 1.0? is there anything else i can adjust other than the "TPS adjust screw" ? cause that seems to adjust in very fine increments. like is there another screw i can turn for bigger adjustment?

nope, the throttle plates are closed but the TPS's wont get down far enough for some reason... i've tried adjusting 3 screws on the throttle body and none of them have gotten the resistance down anywhere near .9 kohms

sounds like a bad tps, you should be able to turn to screw and get it to 1k ohms if you can't then its most likly a bad TPS....but then again I am not to familiar with the S5 TPS unit

did you move the safc at all? the flimsy POS cable on it can come unplugged inside the safc VERY easily. simple tugging can loosen/unplug it even when you don't think you've pulled that hard. take off the 4 screws on the back of yours and check it. i checked mine before i even installed it (got it used) and it was already unplugged. my buddy was moving his and it came unplugged too..took him forever to figure out what was wrong with it.
