Son has 89 Saab 900 S Turbo with about 80,000 miles. Two months ago, after filling up with 87 Octane mobile, the car started riding rough ... after a brief warm up, the car would not "rev" when giving it gas ... you'd be driving, and all of a sudden the engine would just idle, even if you pressed down of the accelerator. Changed the fuel filter; that didn't change anything. Added Slick 50, and that worked for one tank of gas. Changed to high octane detergent and that seems to work. Is there something else that might be wrong?
