engine code

hello, i decided to check my computer for codes last night and found my truck to be showing a p0306 code, i cleared the code and it came right back, so this morning before work i cleared the code (truck was cold) and it stayed off, after driving to work and getting truck warm it came back. anyone have any ideas what is wrong, i know it a cylinder 6 misfire. thanks Brian

forgot to mention, for the most part the truck runs great, sometimes when i stand on it it misses a little, almost sounds like a surge.

what year is the truck? what mods? any work done to it latly
the p03XX codes are kinda of uncommon. check harness for damage. odds are you have a failed injector.

ok, sorry i am a retard. i read the code wrong i assumed it was a p code, the code was really a u0306. i know why its throwing that code. when my FICM went out i put a swamps 58 volt one in place. when they sent it back it has the most recent flash in it. my trucks flash is about 2 years old. that code is a miscomunication between the ficm and pcm. i just need to get my ficm custom flashed and it will go away, just have not had the time. sorry for the dumb post.

to answer the question about the truck its an 04 with 5" exhaust, sct w/spartan tunes, k&n intake and 4" lift with 35's
