intake issues?

Bad/ Dirty Maf?
Bad Ground?
Bad ICM?
Bad Fuel Injectors?
Bad Injector O Rings?

We need more information than "I've got a missfire". What codes are you seeing? Hows it running?

cylinder 6 bud.. try swapping coil packs, injectors.

^ This. See if it follows either a coil, a plug wire or an injector, could even just be a plug.

I'd like to keep this to one thread per issue so that we don't have to make the same suggestions again. If this isn't the case, please pm me and I'll unlock for you.
