Trucks been in the shop since Tuesday morning. They've drove it and can't get it to skip or back fire. I don't think they are letting it warm up completely but they said it acts completely fine with them. Any ideas? I don't know how they are driving it so I don't really know anything, it's just frustrating cause they think I'm crazy saying it's skipping and backfiring and they can't get it to do anything.

Got my truck back Monday afternoon. New spark plugs and coil packs resolved the issue. Truck runs smooth and no skips. I even think it's a little faster now. There's no more back fire or anything so the cats are good. Plugs only had about 40k on them but were I drive like I'm 90 the carbon had built up on the plugs. So for you guys that are with me on driving like your 90 I recommend stomping it some to get the carbon off the plugs. I hope this thread helped someone else in the same boat out!
