Spark plugs are recommended to be changed before 100,000 miles on your Mercury Mountaineer. You should look into getting it done before that mileage or if you've had another problem that may have fouled the plugs. In this case you should replace the spark plugs and not just try and clean them. If you'd like to keep up with your Mercury Mountaineers scheduled maintenance, consider YourMechanic for any of your needs as we can come to your home or office to service the car.
