Engine Power on 2017 Malibu
I didn’t drive the car for about 7 months. I just
jumped it and the engine light came on and a
message saying that the engine power is
reduced. It wouldn’t exceed 10mph or about
2000 revs.
Could it be that the 1/2 tank of gas is bad?
And could I fill it with premium gas to dilute
the bad gas?
