hey guys. i love my car but its giving me a few problems. when i stop for a stop light/sign etc., my idle becomes very unsteady, rising and dropping very fast,(between 1500 to 1700rpm). it does this every time i drive. usually at every stop. every once in a while, it will smooth out and drop to a slightly-higher-than-normal idle. i unplugged the idle control valve when it was running unsteady, and the idle dropped and stayed normal, even when i plugged it back in. this is a used valve. i replaced my old one b/c it was doing the same thing. should i get a new valve? or does someone now that its something different?
