My truck races the engine up to 2000 rpm and will not idle down. When driving and in 4th gear, 5 speed manual overdrive 4x4 it runs down the road fine. Upon slowing down it still revs up. It starts very easily. 5.0 liter motor EEC. Recently changed plugs, distributor cap and rotor.

Check for vacuum leaks and check the idle air control valve.
