I've got a 2000 zx2 that is stalling when clutch is depressed, changed wires,plugs, filters, throttle positioning sensor, still stalls...any ideas?

 

Have you checked for troublecodes? Some of the national brand autostores will read codes for free.In my area, that's autozone.

If your holding the throttle open a little, does it still stall? If it only stalls at closed throttle, I might check the idle air circuit. You may just need to clean the throttle-body.
