Could be just the plug. You might consider swapping coil packs first with another cylinder to save the big $$ just in case you have a spare day.

Also could be the injector, injector wiring or plug wire. I have the same issue with my bosses van. From what I looked up there are too many possibilities.
Seems worth it to get the diagnostic and fix yourself -VS- trial and error on a misfire code. :m2:

dropping it off at dealer on monday will let them figure it out, i changed the spark plugs and moved the coils around, and it still is misfiring. so i'm guessing it must have something to do injectors or wiring?

:(so it needs a new fuel injector and also needs a new fuel rail. the rail was bent somewhere along the line, and the gm mechanic can't put it back with it being bent. pretty expensive fix.
