Been trying to figure out how some guys pedals are rock stiff while others are soft? Any clue? M6. Swapped out TB w/ a friend in his car mine is still firm in his car but his is soft in mine.

What's the trick?

 

The spring on the TB usually does it. You can try coiling it around one more time.

 

I thought about that. But that still doesn't explain why his TB is soft in my car while it's stiff in his. Can it be just a cable loosing it's strength?
