Past 2 years, intermittent problem. Truck runs great for months then begins to sputter and run rough, especially noticeable up hill. Never kills or stalls. Then magically, everything goes back to normal until the next time. Don't have a clue. Auto choke stuck open? Motor mounts?

Do you have a check engine light and when was the last tune-up?

Engine running rough or misfiring can be cause by the following:
1. Defective spark plug.
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. Vacuum leak
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
