Check your main connection from your wiring harness to your coils. It is between number 3 and number 5 coil if i'm not mistaken. If its been unplugged before it may have come loose if you didn't put the safety latch back in place.
I had that problem once, and narrowed it down to the main plug to the coils. Water had gotten in there, and there was buildup from moisture. The easiest way to determine if it is the connection, or not, is to switch the coils from one side, to the other, and see if you still get the same codes, or if it switches sides.
i will do that hopefully its just the main plug , if it is can i just clean it up ? actually ive been having this cyl mis fire on and off for awhile and it never happens under load only cruising speed on or off the highway
