Hi. I have a st mark 5 150 and after driving for about 10-15 mins the car starts shuddering and vibrating and feels like there is some loss of power, almost like it could stall at times.. anyone any ideas?
Mine did that before, can’t remember the part but it had to do with the way the gas tank is pressurized. It would happen if I pumped gas while car was on also died on me a day after getting gas. Brought it in it was still under warranty.
