My coil packs are stockies, i gaped down and the misfire improved but didn't totally disappear.
Checked the coil packs for a lightning show at night and they looked fine, no arcing.
It totally went away after i changed the ignitor module on the rear cover, no i didn't go back to open the gaps again as she was purring like a kitten to well over the redline.
Next weekend ill pull a plug out, 1 heat range colder from what i remember last i had them out.
Edit, shes been fine for the last 2 years like this but just develop a misfire at 1500-3000 rpm 2 weeks ago. It corresponded with the idle speed going up to 1400 rpm.
Solution...replacing the throttle body and intake gaskets right now, they were blown.
