You have a catalyst damaging misfire. This is a misfire that can ruin your catalytic converters. It may only be happening over 80 mph becuase of the amount of load the car is under at that speed. I would start by checking the condition of the spark plugs and fuel pressure. Do not drive much longer like this as it can cost a lot to replace the cats. Alex
