As a diesel mechanic for 30+ yrs I will make a few suggestions.
1, Add some Diesel fuel treatment. Silo, P.S. or Howes are the best IMO but any will do the same basic job. Put 1.25 to 1.5 the recommended treatment if it hasn't been done in a long time. Run the engine at a load for at least 1/2 hr. after this.
1a, At your own risk on this one Dextron II automatic transmission fluid at the rate of 1 pint per 50 gallons of fuel is an alternative to clean really dirty injectors BUT this will boost the Cetane (diesel equiv. of Octane) rating which is good if you have a bad load of fuel and BAD if your engine is really old and close to an overhaul. Run the engine at a load for at least 1/2 hr. after this method also. At your own risk on this one
2, Make sure the air cleaner (if any) is clean AND make sure any rubber hoses are not collapsing at higher RPM's.
3, idle/no load diesels as little as possible and keep them under a load when running or they will load up w/ fuel. Always let them come to full operating temp. before shutting them down if you need to run it only for a little while for charging etc..
