right, engine management light has come on and will not go out, came on after driving up a hill( dont know if that is important or not) then the car lost power and slowed right down, so pulled over and restarted car after 5minutes, car drives fine now but light still on,
any ideas chaps?

oh,untill then the car had been parked up all day (8hours) also dont know if the hot weather would be of any relivance??
