So I have posted this over on mud but I figured Id post it up here and see if anyone has any ideas.
My 2f is missfireing on cylinders 5 and 6. If I remove wither of the two spark plug wires the motor will actaully idle better. It seems that 6 affects the idle the most. It will actually kill the engine if it is hooked up. I had the head rebuilt and installed and had the truck running great, smooth idle and decent power. I I drove the truck for a while and while backing into the driveway last week it started miss firing. I replaced the cap, rotor, plugs, plug wires, adjusted valves and even removed and re insalled the distributer to ensure proper timing. The compression has been checked and is 140 across the board. The plugs come out nice and wet so I know Im getting fuel.
I had installed a new cat and have even removed it make sure its was not blocked forsome reason, it made no difference.
