Nathan - if you have arcing going on, that means that the spark is either not making it to the spark plug, or the spark that is there is weak. This is essentially a misfire and will cause the engine to run rough. The wire is bad, it should be replaced. You might as well go ahead and replace them all - you have to buy a set anyway. -- Mike -------------- Original message from "Nathan Sobieralski" <valleyrat12@xxxxxxxxx>: -------------- > Thankyou warren, > > I think I have two unrelated issues with the car.
