I have a 89 bronco, 300 I6 and c6 auto. Once in a while when I park it to run into a johnny stop or something. When I come back out to go, it won't turn over. If I put the shifter in neutral it will start is this just an adjustment issue. It wasn't a big deal before but it is starting to become more frequent. If I knew what it was I would search it. All I know is it is annoying. Any suggestions?
