Work this one out for me because im stumped
got a missfire throughout the rev range and its cylinder 3 thats down.
Tried 3 working coilpacks - still the same
swopped leads round - still the same
cleaned and swopped plugs round - still the same
all leads are sparking as they should bar the lead thats connected to cylinder 3 on the coilpack getting a spark so strong that if you remove the lead off the plug it sparks all round the plug hole.
cylinder 3 is getting fuel as the end of the pug is wet.......
Any idea's as im stumped
