Hello, I've been doing alot of miles after not long buying my 197. I can't help thinking that when I'm up to 70/75mph, its really sluggish to accelerate any faster than this, the car is a late 57 plate with about 60k on it, the engine generally feels a little laboured even when pulling away from 0mph, could there be something wrong with the vvt actuator? Or any other suggestions? Cheers
