I got my 308 couple weeks ago and serviced it straight away as it had no proof it was serviced recently and since I’ve done it, I’m getting a slight hesitation when I let off the throttle then reapply like it’s got a misfire type thing but doesn’t happen all the time. When cruising at 68 on cruise, the car feels like it’s being held back but if I go 70 at 2100 rpm then it feels a lot smoother and it’s baffled my head. My temp gauge also moves between 80-90 and doesn’t sit at 90 like my partners 308 so I’m kinda pulling my hair out about it because my main car is going off the road for winter so I need this 308 running smooth for winter. Thanks in advance and sorry for waffling on. ?
