1999 Dodge Ram Cummins P0216 Code: Intermittent Engine Failure and Fuel Additive Impact?
I've been consistently receiving a P0216 diagnostic trouble code on my 1999 Dodge Ram 5.9L Cummins diesel truck with an automatic transmission. The issue is intermittent, and the engine tends to stall or hesitate when shifting into gear or reverse. My brother recently added a full bottle of Power Service fuel additive to the tank along with approximately 10 gallons of fuel. Could this have caused the erratic behavior? I'm seeking advice on whether fuel additives like Power Service can interfere with engine performance or trigger P0216, especially in older Cummins diesel engines.
