98 5.4 misfire on #4.. Not c o.p
I have a 98 5.4 with number 4 misfiring. I'm not new to the fact that this is common. Did all normal steps to diagnose(new cop, plug, check hole ect).I have went as far as replacing the entire wiring harness, and still have the misfire. I have an edge programmer that informs me of all codes and all I get is #4 misfire. Anybody else had this issue before? Now all of this started when I changed my passenger side valve cover gasket. Any input helps!!
