Thanks, Djunk. I passed on the PDF and links to my mechanic.

I do remember a "check engine" light the last time the Montero was running (very few and far between), but have no idea what it was indicating. I reminded the mechanics to see if they noted that code.

The engine seems to be getting fuel as I could smell it the last time I tried starting the vehicle.
