Unless someone chimes in my next plan of attack is:
- re-check the function of the DPFE
- new Autolite 105 style plugs that are supposed to be a bit longer than the 700 series I now have installed
- remove injectors for inspection or cleaning
- check fuel pressure
- install new fuel filter (current one has 15,000 on it)
Thanks to anyone who offered help previously.

Just before to make another attempt, maybe you could just check the spark plugs ( at least the 3 one at the front) and see if there are clean; my winnie has a lot of milage, and from time to time I have to clean 1 spark plug ( fortunatly at the front of the engine), because the valve seals leave a little bit of oil coming inside of the combustion chamber, and cause a light misfire of the spark plug.
