shuttering at take off

[cntt]

sometimes I get this shuttering at take off, only happens after having driving the car for a while, when its cool start and let engine worm up to normal temp, then take off, it doesn't happens, only after driving for a good few miles, then stop at traffic or lights, and take off again, I can feel this shuttering, if I play with the clutch to some possition I can take off smoothly

 

any idea what that might be? I couldn't figure out why it only does it after driving for a while every time after it cools down before that will happens, it has a new clutch fitted not very long ago.

 

cheers

What clutch do you have now ?

And how long since your changed your sparkplugs ?

Do the revs jump up and down or does the engine hesitate?

not sure which clutch, it was put in just before I got it, it doesn't say on the reciept, I was told it is a uprated clutch, its afeels a little stiffer than a normal clutcl but not as stiff as the stage 2 I had in the ITR before. speaking of that I remember now when I first got the ITR it was a uprated clutch installed when I first got it and it was the same till I put in the stage 2, except in the ITR it does it all the time no matter how I play with the cluch and throttle, warm or cold, the only same thing between them was that if I take off quick with let out the clutch quicker, its fine.

 

smooth changing gear

 

rev doesn't jump and engine doesn't hesitate at all.

Clutches judder more when warm, points to clutch problem.
