Iv got wasted spark on my 3dr last year it was working but not reading right when the motor was running at about 6,500 it would be showing about 5,800 . well that was last year its been off the road for the winter and its back out now and now the rev counter will only rev to 2,500 and when the car is ticking over it shows 500rpm so im going to have to sort some thing as well
