Check engine light
Returning to Houston from Lake Charles, the check engine light illuminated and the warning bell dinged. All the temperatures were normal. We pulled over and shut down. I opened the engine hatch and looked to see if there was anything obvious wrong. No water in the fuel indicated but I did try to purge the filter to see if possible there was air in the system. Restarted the engine and no check engine light. Returned to Houston without further problem. Anything I need to check?
