The car has 87,000 miles on it. It passed smog just last year with 82,000 miles. I experimented with various grades of gas and settled in with regular grade because I got the same mileage regardless of grade or brand. It took all year to slowly strangle the engine until I finally decided it had to be the cats. I can't find the cause but I am happy for the cure.
