On my 17 Forte, I sometimes have to leave it outside the garage (due to friends/family coming over and blocking my entrance) and at night I put it back in the garage. The two times this has happened, the next morning, the car has a very rough idle that does not vanish for 4-6 minutes of driving. When I first turn it over, it's very rough and at each stop light/stop sign it continues. But after a few minutes of driving it vanishes and won't return unless I specifically have a very short drive, like from drive way to garage short.
What's causing this?
