whenever i start my car my idle jumps to 3k for a second (normal) BUT then its comes back down to 1k and bounces from 1k-1500 until it warms up... anyone know the problem? it goes away when it warms up but even when i give it a lil gas up to about 2k it bounces from 2k-2500.. any clue?

I had a fluctuating idle issue myself when my car was stopped and the clutch was engaged. I called a rotary specialist and he suggested the clutch switch might be bad. Turns out I had a broken spring in my clutch switch which is located behind the clutch pedal. All you have to do is unscrew the clutch switch from the pedal and open the switch using a flat screwdriver. Inspect the switch, clean it with alcohol and make sure the spring is in one piece. If not replace the spring and you should be fine. Or you can just purchase a new clutch switch- shouldn't be that expensive.
Also make sure your idle is @ 850 rpm in neutral after the car is warmed up (drive for 10 minutes). adjust idle screw at top of manifold with black rubber cap. Clockwise to idle down... and counter-clockwise to idle up.

My idle is PERFECT now!
