I recently hit 100,000 miles on my '13 1.4L rs lt. Replaced the valve cover, water house, inlet hose, and a gasket (dont remeber what one). New battery last week. Car was in idle and just shut off today. Started right back up and has done this 2x in one day. I'm going to get my alternator tested just because, and I know my purge valve canister is needing replaced as it has the loud ticking. My question is, would this be what causes the car to shut off? I did notice a gas smell once today. I'm just trying to diagnose the problem before it doesnt start at all.
