To add to what Dono said,
The O2 sensors would show low voltage which is lean, then fuel trims would add fuel and the real mixture would end up rich.
A rich mixture is not good for and engine, excess fuel washes the oil off the cylinder walls and rings and even gets into the oil and thins it out which can lead to bearing wear etc.
A lean mixture is not good either, raises cylinder temperatures and leads to detonation and piston damage etc.
