My check engine light popped up the other day....90k miles ... seems like the common reason for the check engine light coming on is due to a bad 02 sensor. But can this cause a loss in power? My acceleration is not what it used to be. Thanks for the feedback.
it will affect power because the car is essentially running in safe mode (like a computer sort of) because the signal is bad to the DME the car runs the car in a sort of "safe mode" where the car purposely dumps more fuel into the car then normal to compensate for any possible situation that the car could run without the readings of the O2 sensor. this is why its typical to notice poor fuel mileage and somewhat poor performance .
