1996 1500 weird idle.
Having a little problem with the idle on my truck. WHen i start it in the morning it will rev up to around 2 grand then drop to below 500 and almost cut out. Once the truck is warmed up and i'm driving, i can push in the truck and the idle will stay at 2 grand, then drop, then go back up. I'm thinking idle control valve. any input?
Thanks!
Thanks!

Pull of the air box on top of the throttle body, crack the throttle wide open, and look down in there, see oil? Plenum is blown.
If it hasn't been done on your truck yet, it is a good idea to just do it. Get the hughes plenum plate, and install kit, and down the road you go. about 140 bucks total, including shipping.

It's a vac leak somewhere. Check the throttle body gasket. It's likely the plenum. On mine, I had blown intake gaskets on the #7 cylinder port, blown plenum, blown throttle body gasket, leaking injector o-rings, and a split PCV hose. The whole manifold was one giant vac leak. Did the plenum and changed all the gaskets, and it works great now. No vac leak.
