You sound quite savvy on these Pontiacs, perhaps you could think about mine. It's '88 Grand Prix and has the too soft pedal, when I got it just a few months ago, it was really great, but then.......................it's high mileage like 167k and doesn't burn oil, and I have to keep it going. The brake indicator is on all the time, but it's pointed at the rt frnt. Any idea? TIA. greg
