another problem...
no i dont have any cats. i have headers to pipe to muffler and turndowns before the rear axle. i rebuilt the engine about 4 months ago. i pulled all the plugs. 2 was black, and 3 was not working at all. i changed them both and it hasnt misfired since. my cam is a slighty bigger than it should be, so it doesnt idle right as it is. but im pulling the engine again and going bigger in april.
