I have been getting a vibration through the front end end and in the steering wheel if im at say 2k rpm and let off the throttle at 2800/3000rpm after giving it some. it only does it in this rpm range and it doesnt matter what gear im in, im confused to as what it could be. anyone had this before? its rpm related and only does it if i give it some within this rpm range, if i drive sensible it doesnt happen.
