Both the coil and the ignition condenser can fail after heat builds up and yet, when cold, can work properly. If you have had your original Ford coil rebuilt by Skip Haney, I would suggest it is most likely good. Who manufactured your plugs and what number are the plugs? Does your engine have a heavy battery ground cable bolted to one of the head studs? Which cylinders are not firing correctly?How do you explain the plug electrode being bent when you checked plug gap before installing?
