I have a Ford Mustang 302 that is Misfiring. It has an aftermarket MSD electronic ignition so it has no points. It was running smooth until I changed the belts and leaky power steering pump. I replaced the spark plugs and checked the wires. It stops misfiring when the engine warms up. But before it warms up it misfires terribly and stalls. I want to check for a burnt valces but I can not find the correct compression because it is a 1965 Mustang with a 1969-71 V8 motor. help? Any expert opinion on this? :im confused:
