By two bottles of fuel injector cleaner; Pyroil or Gumout. Add the cleaner to about 1/4 tank of gas. Drive until almost empty and refill the tank. This high a concentration of cleaner will clean the injectors but will have a tendency to foul spark plugs; it is best to do this at the start of a long highway trip as you will have to refill the tank at least twice to remove most of the cleaner. If you plan on changing the spark plugs wait until after you use the fuel injector cleaner.
