I bought it at a Gm dealership. It had a complete tune up. Fuel filter, cap and rotor, new wires, new spark plugs, set to specs ( I pulled them and checked them myself ) new air filter, The lifters were checked and set to specs. The timing was checked and set to specs if needed. I also saw the work order for it. The truck has a throttle body on it. I was wondering if that had something to do with it or one of the sensors. I can normaly find the problem. But this is a stinker.
