Random misfire while cruising
Yesterday I noticed my car bucking/misfiring at highway speed, around 70-75. My tach needle would also jump like crazy. WOT is fine and idle is fine.
So far I'm thinking bad coil, bad wire, or bad plug. Up till now ,it's ran fine! This was also sporadic. It would act up like that then be fine for 20 miles.
I already ordered new wires, a new coil, and some better wire retainers which mount to the valve covers.
I have a Mallory ignition setup, aed 750 carb, roller cam, edelbrock etec 200 heads.
