Hi all
Had the 2500 saloon out the weekend all running very well.
Then there was single missfire, or more like a large jolt! Then a couple seconds later the same again.
The next 40 mile no problems at all just running normally.
Any ideas what it could be?
I have fitted the following new parts NGK plugs, HT leads, Pertronix electronic ignition, rebuilt distributor, red rotor arm,and dist cap.
