I have a 1965 nova with the original 230 straight 6. It has low miles on it and runs good except for the misfire I cannot solve. The #2 spark plug keeps fouling out. All the ignition stuff is new; plugs, wires, cap, rotor, as well as the gaskets like the intake manifold, etc. I have run a compression test on the engine and they are all within 2 psi of each other. I have tried spraying carb cleaner around to find a leak and find nothing. It is only the #2 plug. I even tried swapping plugs to see what happened, #2 fouls out. Does anyone have any ideas what might be causing this. I am going insane with this stupid misfire. Thanks for any help in advance.
