Needing members advice....I bought a used 2019 chevy equinox for about 6 months now. The car ran great. The other day I filled the tank with E88, (88 octane). After about 60 miles my check engine light came on. Code PO171, lean fuel to air ratio, meaning a bad map sensor or O2 sensor. I don't think its a coincidence throwing this code now, and thinking it's related to the E88 fuel. Can this be ? Appreciated all comments.
Threw code PO171
