A self induced problem that appears to have healed
This post pertains to my 2005 Newmar KSDP 3910. ISC on a Spartan.
I had a couple of senior moments in quick succession yesterday. I pulled into a place to fill my propane tank and when I turned the engine off, I did so with the Allison still in gear. Realizing that, I turned the ignition to the “on” position to light up the dash and hit the neutral button.
When I was ready to leave, I started the engine and got the “check engine” with an audible alarm. The engine was idling very roughly. Surging actually.
I then shut it down and disconnected the chassis batteries for a couple of minutes. After reconnection, I fired it up and the check engine was still on.
I decided to try to get home anyway and got back on the road. Within a couple of minutes, the check engine light and alarm went off and the coach seemed to be back to normal, including a smooth idle.
What the heck happened?
