ive seem to have lost nearly 2000 rpm. i cant get my stg1 saff to rev past 45000rpm its a process of ilimination im nearly there i thinks. i checked the tps readings with multi metre and throttle plate shut its reading 4.81volts. and wide open its 0.44. shouldnt this be the other way arround. would this be because its got 4wd tps with the outer wires swoped arround fitted to it. i measured this of pins 1&17 pin of the ecu plug mine is a 2wd by the way. ive not taken the throttle body of yet for a closser look just thought id run it past every body here . i think the propper readings are 0.35 volts clossed and just under 5 volts open. if my readings i have now would this cause me running probs. thanks
