We have a 2009 Versatile 535 with Cummins ISX 15 in it. At low RPM's, it coughs around some. At higher RPM's and pulling in the field, works fine
and all the gauges are fine. Cummins was out recently and said the pressures from the injectors seem fine. Any thoughts on what would be causing
this? TIA
