1995 Mercury Mystique GS 2.5L Excessive Emissions, Poor Fuel Economy, MIL Lamp on, Rich condition
Thanks in advance everyone. This mystique is giving me some headaches. I've had the car for two days now and can't make any headway on it at all. It has codes set for rich condition on both banks. I pulled the spark plugs out and they are new and black as coal...
