Is it just me or does anyone feel that there car gets slugish when the SES light is on.

 

have you pulled the code to see why it might be sluggish?

 

Its a O2 sensor problem, I put the new one in but the light has not gone off yet.

 

you will have to reset the light for it go off. autozone can clear the light and it should remain off if the o2 was replaced. you may want to have them pull the codes again and make sure another has not popped up.
