93 engine, mostly stock, I have a high idle. I first thought my throttle cable or my throttle body was sticking, but here is what is happening. It usually idles at about 1000 rpm, while driving the idle will climb to about 1500 and has been as high as 2500 rpm. If I hit a bump, it will go up or down, very erratic. I dont know what to make of it. I checked the cable and throttle body and there seems to be no binding or rough travel, is there another part I need to be looking at? Maybe a vacuum line somewhere? If the idle is high and I am where I can shut the engine off, when I restart the idle is fine, only when I drive it does it do this. I dont want to take it to the shop, but I will if I have to. Any ideas would be greatly appreciated.
Thanks
