1996 Volvo 850 4 cyl Front Wheel Drive Automatic 125000 miles
the gas mileage has been bad since the light came on. Autozone couldnt find where to plug in the scanner to see what code it would show to see why the light is on. But I don't want to spend the money for my mechanic to scan it and not be able to afford fixing it. What does it sound like the problem is. Just ask for more info if needed to answer.
