Hi all. Took the plunge and got a Red '06 GT with decent service history and 70k miles. During my test drive i noticed a leak in rear silencer and managed to get a small discount from the owner. However, on my way home car started to jerk and losing power when accelerating. Also a motor control system failure error message. When driven gently, it goes smooth but soon as i put my foot down it's loosing power with the error message. At the moment the engine light stays on. I will sort out the exhaust tomorrow. Do you think it's related? Thanks!
