Not a big deal ... I would decarb motor, though. How do you know that cylinder is misfiring ?

when i could not get the motor to run smooth/wot i considered it an electrical issue and i started pulling the plug wires while running and felt the plugs when it was not running properly and it was "cold". changed all plugs, wires, moved coils around then the motor would run fine and then cut out,then the check engine light started coming on. so i now figure the running issue is fuel system related.
