Okay everyone im having problems with what i think is my clutch and chattering but it only happeneds when ive driven my car for around a hour, it is a 5 speed 05 gt, and it slowly gets worse as the car warms up ive had it in and i told the guy he didnt drive it long enough, and he said thers nothing wrong with it, what could be wrong please someone reply asap as the car is in the garage right now

 

Take it to another shop that is willing to put the time in to fixing it?

 

Did you take it to a stealership (oops I mean dealership)... or
a regular shop?

 

its one of my step dads best friends who has ben a mechanic all his life, i told him to fix it cause it gets really annoying when ur trying to show off and the car just shakes to **** after its warmed up
