Check the clutch master cylinder....check if the fluid is low and then check the clutch pedal to see if it is leaking fluid between the firewall and where it cable attach to the pedal....it usually leaks for all manual cars. If it is leaking, replace the CLUTCH Master cylinder (not the brake master cylinder, they are two different units), if you're cheap, then take it apart and clean the inside of the Clutch MC (usually gunk build up)....Then, flush the with dot3 or 4 brake fluid, bleed the system properly, and refill with dot 3 o4 brake fluid...Hope this helps ur problem.
