It came on THAT night I had the official one put in So it's definitely the mods no doubt about it... errrgh I'll let JamSport fix it
doing my nut in on and off on and off... ...To Kev: Yeah I'm going to look into protecting these cables/sensors from too much heat because that's what started this all off. I went on the rolling road and the sensor REALLY didn't like it lol ...To Drifter: My performance is fine mate its just the light goes on and off all the time! I think you need a throttle body clean maybe or cylinder check?
