Hi all, i ocasionally get a dirty misfire on my astragte8v, if it happens it would be by planting the accelerator after travelling at a constant speed. The cars is running new (300mile) spark plugs and did misfire a couple of times before with the older ones.
The only thing that looks suspect is that the lead from the coil to the dizzy has a crap conection, on the coils lead as there is a cable tie around it, it looks secure but isnt right.
what else could it be? i have no idear when any componets were changed and the cars done 156 000 miles.
any cheap fixes are welcome.
