2015 Newmar 2903 Baystar.
For the last year I have been chasing a problem. The engine would miss like a clogged fuel filter. Many mechanics worked on the problem. They would say its fixe and in a short time it was back.
The following was done, throttle position sensor, throttle body, mass air flow sensor, rest the computer to relearn, and completely strip computer of program and reload.
Finally a good mechanic found that there was noise in the mass air flow showing on the computer. The wire harness, which is the engine management harness had wirers placed in the harness by Newmar. The wires to the mass air flow where replaced with new shrouded wires to correct the problem. Hopefully this is the problem and it is fixed.
HAS ANYONE HEARD OF SUCH A PROBLEM
