Need help! Running Bad.

hey guys i have a 05 f150 5.4 that is giving me issues. it all began one raining day on the way to work when the engine light started flashing. that day the code was for a crank shaft sensor, i replaced it and the next day i was pulling a trailer and the truck began bucking every now and again. threw a code for coils a and f. i swapped the coils. same code. changed the plugs. same code. changed cam shaft sensor.. same code plus p0320. tomorrow i am changing the crankshaft sensor again hoping that maybe it was just a bad sensor. i moved wires from around the AC condenser and all that but still same code... but one thing i have noticed is when it does buck or run rough the ac stops blowing cold.... which is something i haven't seen on anyone's posts... any ideas?
