My merc has 97,000 miles on it. It runs good except for when the outside ambiant temperature is above 70. Then it runs rough and sputters, especially between 50-60 mph. If i give it gas it takes off, and doesn't do it when it is cooler. i plan on getting new plugs at 100,000. Could it be anything else. No engine lights, or other warning lights are on.
