Hello all. A few days ago I started my wife’s 17’ SFS and it sounded/felt rough on startup, like it was sputtering. This lasted maybe 1-2 seconds. Then this morning my wife called to say that while she was reversing into a parking space, the sputtering came back and she thought her SF would die. I am thinking it has something to do with possible bad gas. Has anyone else experienced anything like this? I’ve never had experience with using bad gas.
