Bought a 02 Dually with the 5.9HO lost Fuel Pump and Injector Pump in
600 Miles. Replaced both no codes drove 700 miles@ about 72mph, then took an exit. Stopped at first light after leaving the "SuperSlab" and Truck fell on it's face pulling away from light..check engine light came on, put it in Neutral coasted 50 feet back into 2nd and had full power (confused) Drove about a mile it did the same thing. Parked the Truck at the house next morning went out did the key deal obtained a DTC of If I remember correctly 1693 but no other codes. Started Truck check engine light went out and has ran fine since. I know the 1693 is a generic code. The only other point that I might add is the 700 miles of driving was in temps of 12F or Lower and engine temp dropped from the normal 190 to 140 at the first light. Is this just a freak because of the temp and then stopping or should I investigate further?Any comments appreciated.
