High idle when started.....
Whenever i start my truck the engine revs up to about 2 grand then drops back down almost dies then idles normally...It is an 88 f150 with a 4.9 and 5 speed. it has 70k on replaced engine. I just changed the plugs, wires, cap, rotor...Hoping that would help it run better but it still doesn't run well
