peg777, it would help to know some additional information about your 1989 300E ... mileage and whether or not you perform routine preventive maintenance described in the Service Booklet. Sluggishness could be that it needs a variety of things ... fuel filter, spark plugs, distributor cap & rotor, ignition wires, coil, oxygen sensor, etc.
