Replaced with new cap n rotor yesterday, same problem. Also have a few of the parts inside the distributor. Replaced with a few already and same problem, well one time the dead cylinder went from #6 to #2, weird.
Will do a compression test later when it gets a bit warmer here. Thanks for the advise everyone and if you guys have any more suggestions, much thanks in advance.
Will an ecu cause this problem or is it just the trigger inside the distributor the main controller for spark?
