    Are you sure you didn't get the front and rear harnesses mixed up? If you put the front harness in the rear and the rear harness in the front the wrong injectors could be getting the signal to fire.

    Mine was coding low voltage to vva on #1 and #2. Replaced the harness and All my vibrations, driveability and atrocious fuel mileage problems disappeared. $1400.00CDN parts and labour at Kenworth in Ottawa. Fuel savings covered the cost in a month.
