Ok guys so ever since I got my s13 I've had this issue. Usually once or twice a week sometimes more she wont shut of I can take the key out and everything and she stays running. Now obviously im leaning towards an ignition cylinder but I wanted to get everyones feedback on this before I go buying a cylinder. Is there anyway to test it? Why is it intermittent? if it was the ignition wouldn't it happen all the time? And last does anyone have one laying around d they can sell me if so?
