CEL codes P1204-P1206 and P300?

[topgunsnsx]

Was driving and got a blinking CEL light. Pull codes P1204, P1205, P1206, and P300. What can be the problem that's affecting cylinder 4,5,6 to misfire? Thanks for your help.<!-- / message -->

First thing to do is reset the ECU and see it it was intermittent or a hard failure. Could be Ignitor, Misfire Detection Module, loose wire. But....let's see if it is goes away first.

The other thing to check is your front coil cover and if the cover has the seal on it, Did this happen in wet weather driving?
