Engine sputtering at low speeds
Howdy again from the road!
So after driving through Pueblo, CO I noticed that suddenly at low speeds my engine would seemingly go to a low hum and I would lose all power, sputtering until after a couple seconds when it would come back to normal. Running wide open I have no problems, it's just at lower speeds.
I figured I might have a fuel filter issue, so i replaced them and used some biocide in the tank to make sure that was clean as well. After this, she ran better than ever and we drove about 70 miles to our new spot. Once we got to the site and stopped/went back to lower speeds the problem came back!
