18014/ P1612 Engine control module incorrectly coded 35-00
P0300 Random/multiple cyl misfore
P0302 Cyl 2 misfire
18014 Rough Road/Engine Torque signal from ABS; Electrical malfunction

Switch the #2 coil pack with another. If the misfire doesn't move from #2, your ICM is bad. Replace that. The ABS one is probably just a one time fluke. After you clear all the codes see if they come back. Oh and google Ross Tech Wiki.

Did that, misfire stays on number 2, replaced the icm, was good for about a week, started again
