Anybody got any ideas my car judders (whole car)after I release the accelerator after a hard acceleration for about 3-4 seconds doesn't seem to be speed related as it happens from what I can work out it seems to happen more going up hills just had all tracking and balancing done, I thought it could be either torque coverter or be over fuelling anybody had anything like this before

Many thanks 07my 3.6 tdv8 vogue se in red
