This can be caused by one of two things either the ignition system is back feeding into the tachometer circuit or the tachometer itself is going out. Can I ask if the engine is misfiring? If it has been a while, I would change out the spark plugs, cap, rotor and spark plug wires. Here is a generic guide to help walk you through the steps with instructions below for your truck.
