you need to adjust your clutch pedal

look under the dash, there is a metal rod that goes into a fork with 2 nuts. loosen the 2 nuts then rotate the rod.

spec is .5 inches of free play on the pedal before you feel any tension. you may have to adjust off of "spec" to get a proper feel.

I dont think that is it. My pedal wont even stay up, it just falls to the floor. Also when i bled the line, there was air bubbles but there is no leaks in the line. Possibly a bad slave cylinder?

you neglected to tell us that part lol

and did you get all the air out? sounds like air could still be in there.

gravity bleed.

open the slave bleeder. open the cap on the clutch master. watch the fluid drip. may take a minute or so for the fluid to come out. but it will come out in a steady stream once its bled.

you dont have to touch the clutch this way and it insures its a good bleed. if your problems are STILL there check pedal adjustment, and it that still dosent fix it looks like its time to replace the master and slave.

Ok i did that. I got a good steady bleed. Pedal still wont work. SO i changed the slave cylinder but i swapped it out with a ka slave cylinder. It was just a little bit bigger but it fit real snug. But i tried it again, eccept now it only drips and no stream. I dont know what is wrong. I dont know if this matters, but i havent done any of the wiring for the transmission yet..i dont think that should matter, but who knows.LMK!
