Hi,

I have a MK4 Golf 150 which has been chipped and runs fine. That is until im in either 5th or 6th and accelerate from low revs. At about 1500 and also 1900 rpm the car shakes quite violently until it is out of these rev ranges. It sometimes does it in fourth if I am going up a hill, but it is always at the same rpm.

I had the clutch replaced in November and have noticed this judder for about a month now.

Any ideas anyone?

Thanks in advance
