I have a 1987 Chevy pickup with a 350 ci fuel injected, throttle bodied engine. All of a sudden the engine has developed a high idle. It idles at about 1700 rpm. The only code was for the egr valve which was very dirty and plugged up. I replaced it (leaking diaphram) and fixed a couple of vacuum leaks and figured the problem was solved but it wasn't. It has been tuned and I am about to pull my hair (all three) out. Runs good except for the high idle. Any help and tips will be very appreciated. Sad

Fixed the high idle by cleaning the throttle body and doing a repair kit on it. Basically a good cleaning and changing the gaskets and o rings.
