Hello I am having an issue keeping my truck idling on its own. Here is the history on the truck. 2000 GMC Sierra 1500 4.8L automatic with manual 4x4. Bought from auction as a flood vehicle. Water was in the engine in the oil and in the cylinders. Got that all out and new plugs, wires, new fuel, oil and filter. The truck runs now but it will not idle on its own. If you give it just a slight amount of throttle it will run. If you let off the gas it dies. I checked the throttle body and cleaned it. Clean air filter. The fuel pump primes 50psi but I haven't checked it while running. Any thoughts as to why it wont idle on its own? It will rev all the way to redline and you can drive it around a little if you two foot it. The engine sounds healthy but wont stay running.
