I think the new plugs still have a skip. I think it's better now because when the engine was cold it seemed better but that could be the gap on the new plugs is 0.025". All the old plugs looked the same as far as color of the porcelain at the plug gap.

Now I'm wondering if it is ignition problems. Only thing not changed are the plug wires and the distributor pick up coil.

Also my throttle is sticking now at 2000 RPM unless I punch it. Of course no sticking with the engine off.
