i have a 2001 Audi A3 1.6 sport and i was driving along and the check engine and traction control light came on it also was running very rough, i had it checked on a diagnosting computer and it come up as cylinder 4 misfire The spark plug in cylinder 4 had failed so i replaced the spark plug in cylinder 4 and it has run fine for around 100 miles and the problem has returned, anyone know what this could be. Thanks
