I have a 2015 with 1600 miles...yes, the damn this is brand new. On my way home tonight, I was sitting at a red light with the clutch in and gear in 1st. I moved the selector to neutral and let the clutch out. The engine idle dropped and the engine felt as though it was going to die. I gave it some gas, the rpm settled and the car began idling fine once more. It happened again, same situation, maybe about 5 minutes later. I've heard that some Focus ST owners have been having similar issues. Anyone with FiSTs? Any info or insight would be appreciated. Not sure of this matters: Just before this happened, I filled the car with gas from empty (gas light came on 5 minutes earlier). I use premium all the time.
