Scanned the car today and 4 misfire codes showed up.
P0300, 302, 304, 305 on top of the pending 442 code I never erased.

Any possibilities other than secondary ignition parts? I did find a track mark on the coil though. Other than that the car runs like a champ and pulls hard under a load. The old plugs were worn. They were at a .037 gap. New are at .028. No vacuum leaks were found either.
