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

You might try this web site, look under Scooby Page, then Workshop Manuals, then Workshop Manual for PRE MY97. It should give you the trouble shooting info you are looking for.
