We were on our way home after staying a night at Blue Ox RV Park in Albany, Oregon, when a check engine light and malfunction indicator light (MIL) came on the dash. Uh oh!

The fault was ECM SPN 102 FMI 18: “Engine – Engine Intake Manifold #1 Pressure. Data Below Normal Operating Range – Moderate”.

So we stopped at the next rest area, and I followed ChatGPT’s instructions on what I could see in the engine bay, but the fault was apparently likely somewhere that I couldn’t reach (and probably wouldn’t have been able to fix anyway). It was a Saturday, and Oregon Motorcoach Center was closed until Monday, so I made a reservation at Blue Ox again for the weekend, and we headed back. Sigh.

Back to Blue Ox; at least we didn’t need to check in at the office; they called us and said they’d check us in:

Our site, #145; we asked for one site over to give space to the neighbor, and for better Starlink signal (there was a tree partially obscuring our Starlink in the previous site):

Coming back here was not what we had planned to do with our weekend, but I’m glad we weren’t too far away, and Blue Ox had availability.
