High me again i have just had my car serviced and previous to the service all was well, since the service my car has started to jerk at higher revs when accelerating normally no issues but once the power kicks in and the car starts to accelerate hard it jerks quite hard and seems a little hesitant. I have done some searching and some say plugs and some have pointed to the coil pack having only had the car a couple of weeks and just getting the jobs done im new to these cars, does anyone else ever had this problem or could anyone possibly shed some light thanks again Mick.
