I went with steeda for mine.
Question: Is your cable riding against your Header/mid-pipe?

Directions say to try to keep it from the heat the best you can.
And as MD said above how far did you have your clutch cable adjusted?
Did you have your clutch so you barely have to touch the pedal?
And Mashed it to the floor a few times?

 

i had it as soon as you touched the pedal but i found a website that told me what i needed to do and i adjusted the cable to much i had it to tight so it rubbed on the inside and messed up the cable so i have it adjusted to engage at the height of the brake pedal and it works great RIGHT NOW

 

take the firewall adjuster off,and put a new cable in try it
like that for a month and see what happens.

 

i think its been my fault the whole time bc i have been tightening the cable to much and i just got the firewall adjuster this last time so its not the problem bc its happened to me 2 other times without the adjuster

 

f*ck adjustable clutch cables. My stretched everytime i bought one. Last one i had was a mustangtuning.com cable and i pulled it out and from teh firewall it was all frayed. I put the stock ford one in and it was fine. Havent had a problem since.
