Not sure really what it's actually called but my car is suffering really badly now and every time u get going after the car has warmed up, it happens fuel cut/surge for a split second it dies then ok again then dies, its gets that kangeroo feeling and is fooking me off summit rotten now, just finished doing my 1k miles running in my new engine and is due to go back to be serviced and re-mapped, will remapping get rid of this problem or is it caused by something else ? is so what ? and how is it rectified ????

any help is appreciated as its fooking annoying as u drive down the road and its starts acting up

 

Get it checked out ASAP just in case it is running lean. You may quickly kill your new engine otherwise
