you might want to replace your plug wires

Just to let everyone know what I found to be the problem. The engine has an aluminum head. As stated in my original post Cloninger Ford of Salisbury had replaced my coil pak and plugs 22,000 miles previously. When I went to remove the four plugs three of them came out without the need of a wrench. The white of the ceramic and the boots were literally covered with combustion carbon which had blown thru the threads of the loose plugs. This caused short circuiting and the misfiring. Evidently the mechanic failed to use a torque wrench and ended up not tightening the plugs sufficiently. I don't know if there is a moral but I ended up paying to fix a problem they created when they initially repaired the vehicle.
