If you have the stock tune in the truck I would bet this is the problem, Without a doubt.

 

Yeah, longtubes and ORY on a stock tune isn't the best thing. LT's usually require a tune to run right.

 

The Exhaust Has Been On The Truck About 8 Months. It Didnt Start This Crap Until About A Month And A Half Ago. I Figured It Was Too Lean With The Exhaust & Intake, So I Put The Stock Intake Back On....... Occaisionally Checking The Plugs Every Oil Change. They Looked Good Until It Started Running Bad, It Has Burnt 2 Sets Of Plugs In 4,000 Miles.....
