hey guys. hope u can help me fast, lol i was on the motorway today and my car juddered and my engine light came on, pulled over and called the AA, who changed coil 2 as that was apparently the problem, fine i thought as it idled fine, but only when i got on the motorway i realised that its still has a slight misfire when above 3000 rpm?! what could this be as changing cylinder 2 definatley improved it, just not perfect! lol
