Rev falling when car stopped and clutch pressed ?

[CONSIGLIERI]

Hello dear friends ! I'm having a little problem and I hope you can help me...
I've read some posts, but didn't find an answer...

Here's the deal...

All of a sudden, I realized that my rev is falling a little to 700, making my car trembling and ALMOST wanting to die when I press the clutch with my car stopped.

It happens when a gear is engaged (just after stopping at a light).
If I go to neutral gear, it raises again to 900-1000...

What could be causing this ? Could it be the ISC ? Clutch might not be disengaging properly ? Clutch pedal assembly ?

Thanks !!!

could be a throwout bearing thats beginning to go. I'm sorry I havent had to work on my driveline yet so I dont know the entire deets on how or what is down there. An easy test to see if the clutch is "dragging" is to put the clutch in, put it in first, then rev it slowly to 5 or 6 k. If the car begins slowly creeping or if you smell the clutch burning then it is in fact dragging. This happened to me. It was the throwout bearing that was actually bent and eventually just broke.
