Hi all. I have a 1994 impreza type ra n I was just wondering how u do full ecu reset??? I have no idea any help

 

- connect green pair and black pair of diagnostic plugs under the dash
- switch ignition on, but don't start engine
- press gas pedal to the floor, then release it halfway up and hold it there a few seconds, then release it the whole way
- start engine, and drive the car for a few minutes at more than 11km/h
- stop car and disconnect diagnostics plugs

Alternatively, just disconnect the battery for a few hours.
