Hello everyone,
I have 94 WRX ra, I have just had the motor/gbox out of car, now motor and gear box are back in car, its all wired up. While driving the car when i put my foot flat on the throttle, it is surging... feels like a fuel cut. I have plugged the two diagnostic plugs together and it gives me a code '31' which I have found is a Throttle position sensor code. I have just bought a new TPS and fitted it, but is still giving me the same grief... its only when i put my foot hard on the gas that its doing it. If I ease the boost on it is fine... does anyone have any ideas on how to cure my sick subaru? Any help would be much appreciated!
Thanks guys
Brad
