Did the tune up, plugs, cap/rotor, air filter, cleaned out the PCV valve and oil change. Sprayed the E4ME Qjet out with GUMOUT as well as spraying down the throats with the engine running. Took her out on the highway for a 10 mile high speed run at 70, no joy.
Tech suggested a carb adj, and new plug wires.
