Well heres the scoup: I have had a idle/low rpm cruising miss for the past 6 months now. In trying to solve it I have replaced the opti-spark and wires, but the miss is still there. I checked under my hood lastnight after replacing the wires and I can see arching from all the wires between each other when the engine gets hot. The wires are MSD 8.5mm cut to fit because I run them otvc. The wires were put in by a mechanic at my work and he was very careful/took his time. Is it possible I got a bad set of wires, or is this something else like my plugs being gapped wrong?? (the plugs are 12k miles old TR6s) This problem occurs only when the engine has warmed up, and there is no miss at WOT cause its still fast as hell. Also, the only code being thrown is P0300.

If anyone has any ideas PLEASE let me know, this is getting frustrating!
