So today I am at the beer store. I stop and talk with a friend a moment after I turn off the engine.
When I start it again the dummy check engine light comes on, gear indicator shows "4" and will come out of "4".
It also will barely move so I shut back off, check fluids and all OK.
When I restart it no longer shows "4" but the check engine indicator light remains on.
I did fill up a couple days ago with about 15 gallons of diesel, but had not driven it since then until today.
It seems to drive ok, no issues other then the light is on. And, for what it is worth, 17,500+ miles on it.
I am thinking maybe O2 sensor/s? Thoughts?
