alright, ive been having this problem for a while and i figured since i was putting a new motor in i would check the throwout bearing. well let me tell you the problem first. the car drives fine and shifts fine. the clutch is adjusted properly as far as i can tell, but the clutch pedal has a really bad vibration to it. i can adjust it out but than the clutch grabs all the way at the top. when i pulled the motor i took the throwout bearing out and checked it out and couldnt find anything wrong with it, so i had two buddies who are mechanics in the area look at it and they said nothing was wrong with it...so we put it back in. i dont know if a vibration is what i would call it. the pedal kind of pops and you can hear it, it only does it as the rpms start to get past like 2500. im hoping its not the flywheel because its only like a year old and i dont see how it would just warp like that. someone give me some insight here because everyone i talk to even guys who have owned like 15 mustangs have no idea what it is. thanks guys
