Focus ST Repair Shop / Service
I've noticed that once or twice a month I get an unusual engine stutter from my 2013 Focus ST2. It happens between 1,000 and 2,000 rpm, usually around 1,500 rpm and when I'm going between 30-50 mph. I'm usually in 5th or 6th gear. There is a noticeable vibration and lack of power, even more so...
