i have a 98 t/a with the mods in the sig. all of a sudden it has started throwing 2-4 TPS codes during WOT. only thing is, it only throw the cods at around 80 mph or so then the car falls on its face and afr goes to 14-15. it basically feels like im going from 100% throttle to 40% throttle. a friend of mine had a spare TPS that he's had for a while and i threw it on and the results were the same. is there a chance that both TPS are just bad and i should buy a new one, or am i dealing with something else?

any help/advice? i hate anything that deals with wiring.

what are you volts when you open the throttle at WOT, and what are they at idle? You could be going over the 4.24v ( i think that the max don't quote me) but you can start there.
