I?ve posted before with limited responses, but now I have some more info that might help. I have a 96 Impreza Outback LX with 113000 miles. When in Drive or Reverse and stopped, the car runs very rough. Here?s the thing. If I stop quickly, it runs rougher. whereas if I stop slowly it doesn?t run as rough. Regardless of how fast I stop, it gradually gets better during the time I?m stopped. But as soon as I go and stop again it?s the same thing over again. I?ve replaced plugs, wires, air filter.
If someone has an idea of what this might be, let me know. Thanks,
Barry
