Guys,

Thanks for your input. Got to the RV and connected the Insite. I cleared the fault codes, restarted everything, run the engine and no fault codes (active or inactive).

I did run the injector test and injector No. 1 make no difference when enabled or disabled. All other injectors drop the RPM. No fault code.

Where do I go from here?
