First I wish to thank all of you that posted ideas as to what problem might be the cause of my random missfire.
The cause was right in front of me every time I looked at thye engine, the boot protectors. I removed them and the misfire went away!
When high performance wires are installed, the plug end no longer fits the boot protectors properly causing them to bounce around and in some cases cause random misfires....diegogrande.
