So far i have regapped spark plugs .028, changed coil packs(slightly helped missfire but got worse soon after i installed these), cleaned AFM, cleaned aac valve(rpm no longer falls off when coming to a stop), engine oil changed with full synthetic or synthetic blend 2500 miles.

Have you checked the grounding on your Ignitor wiring harness?
This is possibly the culprit. Make sure its secure and not loose otherwise over time vibrations will make the mis-fire worse and worse.
Other than that I would check your actual CAS and each ignitior to make sure they are working properly.
