Okay, so My clutch is sticking half way to the floor, but the weird part is the car stalls and makes a engagement noise and vibration in the pedal. I flushed the fluid, but I don't think that is it. Has anyone else had this problem. I have searched but haven't found the exact symptoms. If you've had this problem can you let me know what fixed it. Thanx

What kind of car are you working with?
Your profile says a 240 but this is in G series. :gotme

Is it a stumble and a miss then it dies?

In either case I would start with checking for a bug or dirt on the hot wire of your mass airflow sensor.

Check out what Steve said but you may have that problem as well as a slave cylinder problem

When my clutch pedal came halfway up the dealer replaced the clutch slave cylinder and the clutch fluid under warranty last July at 92k miles

The fluid is the most common problem I see.

Many of my coworkers love replacing components without properly flushing the fluid, especially for a sticking pedal.

Thanx for the help guys. It is a g coupe. No misses, only when the clutch is disengaged do it make any noise or anything. The engine only stalls then. Bu I got it looked at and the whole clutch system needed to be replaced. The disc, pressure plate, etc. Everything was replaced. only had the car for a month and a half.
