no but ill do that. and mans its running like a pig
So then it likley really is misfiring on #4. How about compression on that cylinder??? If you don't have a tester, can you pull the plug, put your thumb over the plug hole and have O'girl crank the motor. Or if it's recessed down in the valve cover hold your palm over the hole. Just to find out if it's got good compression.
