Not normal! Is the engine missfiring? With engine idling, loosen one high pressure fuel line at a time , to see if one cylinder is misfiring. Do each cylinder, same as shorting out a spark plug on gas engine. Sounds like you may have a cylinder misfiring , from bad injector nozzle or other cylinder problem. If you can isolate the cylinder, then you can check the injector nozzle , by swapping with a known good one. and you can check the valves on the misfiring cylinder.

Not really rattling along like any diesel does. I have good power as well. Starts right up.

Raw fuel from exhaust always seems to be misfiring cylinder. Do you seem to be getting more exhaust smoke? I would run cylinder test, just to know all cylinders have equal load.
