I have a 94 940 with 175,000 miles. I'm experiencing a flutter or\nhesitation when I'm cruising, 55mph little throttle. I've cleaned the\nthrottle body and replaced the flame trap, replaced air filter. When I\nuse an injector cleaner I don't notice it so much. Im going to try\nusing a better grade fuel, currently use Wal-Mart, cheapest. also\nthought maybe oil in distributor or maybe new plugs.\n\nAny suggestions?
