you could get a pair of uni converters. it wont hurt the performance at all and you wont get a cel
Actually, my "Check Gage" light doesn't come on with the o2 sensors disconnected and no cats present. It shows that it's on when I connect my OBDII scanner, but it doesn't actually light up on the dash.
Also, I don't care to spend money on converters that I don't need just to get rid of a light. My concern is that my gas mileage is being compromised from the lack of O2 sensors.
