When driving with the engine cold. when pressing the clutch the revs fall and the engine stalls. then restarts with a little trouble what could this be? i have changed the spark plugs and leads. however not the ignition coils. engine runs very well once warm.

Do you have a check engine light?

Check the idle air control valve

I have replaced the IACV and checked the fuel pressure and was fine. However same problem still exists. Also Forgot to mention that car is slow and sluggish when cold.
