Replacing old worn fueling and metering solenoids.

First of all, someone needs to check to see if that is the actual issue first. Monitoring the fuel control state and the fuel flow(live mg/stroke) will reveal it. Otherwise, assuming blindly that the ecm is cutting fuel back due to ghost solenoid issues without thoroughly testing for it, is noting but wasting your moneys and time on parts that may not be needed.

There is a correction that can be made to the programming on the CM871 and newer engines to remove that bug, but there again, .. if solenoids are worn out, they still need replacing to ensure the engine is running correctly.
