When I am driving and I put the clutch in the RPMs won't fall to normal idle numbers but instead go down to 1500 or 2000 RPMs until I come to a complete stop. And now my idle isn't acting right eithier. They RPMS won't drop below 1000-1200 now. Which is wierd to me and I don't have a check engine light on.

Any clues? I would figure a sensor but it isn't throwing a light.

Could be a sticky throttle cable. Put your foot under the pedal and try to lift up. If it is, lube the cable. If that doesnt work, then I would think that its your IAC motor.
