Thread: Codequestion

Hi all
Have a question about a code I have its the P0133 and the check engine light is on
Car: 2000 Pontiac Grand Prix GTP
I have a leak in the exhaust, car runs good.

Can I drive this car like normal? Because I didn't feel anything when I'm driving.
​thanks or your answers

You can drive it, but I'd be willing to bet it's running rich on the fuel side. If it is overfueling it can lead to damaging the catalytic converters. Fix the exhaust leak.

Beyond that, if you go with a replacement upstream oxygen sensor, stick with the Denso brand. These cars seem to not like Bosch O2 sensors.
