Replace bad fuel injector
Evaluation of Service Performed:
Had been having a problem, for the last 2,000 miles with intermittent, irregular puffs of smoke from the Cummins 5.9 ISB in our motorhome. 1,400 miles
prior I had it checked by what seemed a knowledgeable diesel shop in Flagstaff, AZ. Their diagnoses indicated nothing wrong. Problem got progressively
worse. With 45,000 miles on Mr. Motor I dropped in on Rocky Mountain Cummins, Billings, MT, unannounced at 07:00 on 8/28/2015. The Service
Coordinator took down my information and had a technician quickly diagnose the problem as a bad fuel injector. Then the Service Coordinator, Karla,
worked diligently and competently with my extended warranty insurance provider to help me get a significant reimbursement. Technician Scott was very
competent and went the extra mile to get us back on the road same day. Cummins has a top of the list hourly rate but I left feeling like me and my
insurance company hit the road again with a high level of confidence in the work performed and got our money’s worth.
