I preformed a minor tune-up, and now my truck stalls after I let off the accelerator. I changed the plugs, wires, cap, rotor and the pcv valve. I double checked the plug gaps and their fine. The truck starts but after I rev it up and let off the accelerator it just die's.

Make sure you didn't forget to replace any vacuum lines. Also, make sure you didn't disconnect any sensors.

Did you disconnect the battery? If you did, the engine computer lost its mind. Just go out and drive it. The computer will instantly start to relearn short term fuel trims, but it needs to relearn minimum throttle. Until it does, the computer doesn't know when to control idle speed, and when to leave it up to you.

Drive at highway speeds, then coast for at least seven seconds without touching the brake or gas pedals. Done!
