Next time you fill up, add some injector cleaner, it may help. If it does use it every 3 or 4 fill ups.

if this is the 600 series engine either 4 or 5 cylinder check valve clearances peform compression and cylinder leakage test to eliminate loss of compression and or head gasket causing loss of power. have injectors tested and reconditioned if necessary. be sure to change flash washers under injectors.

Check valve timing. Timing chains can stretch.
Possible head gasket problem.
Check injection pump timing.
