alright so heres the deal. really dont know wat the problem maybe but heres my issue. my idle reads 1300 or so way high than norm. and my safc reads really high throttle percentages. started off at 18% throttle @ idle but no change in performance or drivability. next day at cold start idle still @ 1300 and throttle percentage at 50+% still with no drivability problems. today it was at 90+% and while cruising 100% and i damn near know im not @ WOT cause im not going anywhere. already checked throttle cable and its fine throttle body is fully closed and still reads high throttle percentages. possible faulty tps? idk.

check the throttle position sensor! maybe the bolts backed out or maybe they've broken. IDK? It may only need to be adjusted.

alright more info apparently the sr motor was an auto cause it has a 6 wire tps..and most stores for ex. phase2 frsport sell the manual 3 pin sensor. is there a conversion for the tps to go from the 6 wire to 3?

Power, Ground and Signal, that's the conversion.
sorry no spoon-feeding!!
