I have a 90 f250 with a 5.8L 5-speed transmission EFI cruise control 4X4. I am the second owner and have owned this truck for over five years and have never been able to diagnose the problem. engine starts and runs normal, however the idle 'sticks' when in nuetral, idles at roughly 1500-2200, when i quickly tap the gas the idle kicks down to a normal 750. any help at all is greatly appreciated. here are my father and I's ideas
1. Automatic choke might be sticking (it is injected so shouldnt have a choke though)
2. Throttle cable linkage may be hanging up, gunked up, or kinked (looks fine however)
3.Throttle body butterfly valve is dirty or damaged (i have cleaned and rebuilt it already)
4.General vacuum problems
5.the cruise control cable is faulty (recently the cruise control went out, the idle problem has been around from day one though)
