As many people as possible, tell me what the symptoms of an erratic idle can be.

My car is idling erratically, up and down around 2 grand back down to 1 grand. The throttle sticks a bit and I pulled off the TB and the plate is sticking itself, no the sensor. When it is very rainy out my car makes a noise and drives like the clutch is going bad (just replace under 16,000 miles ago w/ ACT and new tranny) I know it can't be the clutch because it makes the same noise and revs the same when it is "idling". I ve cleaned the entire intake system, intake utbe, TB, valves, etc. and still erratic idle. Possibly a sensor issue, but no check engine light. Im stumped.

What all can cause an erratic idle?
