So my check engine soon light came on this morning so I went down to the Auto Zone to see what it was.
PO133. Slow Response (heated oxygen sensor bank 1, sensor 1)
That is the front left O2 correct?
I have the back two eliminated with the MIL's from my O/R X.
Auto Zone has the OEM sensor for $46.99. Should I just buy a new sensor and replace it?
Also, my car smells like its running rather rich and not sure how to change it. I have a handheld Diablo Tuner.

Input is much appreciated!

Passenger side front sensor...... Sounds like the sensor took a poo on you. Replace it and clear the code.


EDIT: b/c I'm retarded....

You might want to clear the code first and see if it comes back. Also how long
have you had the x pipe on the car? With no cats its gonna smell some.

I just added the O/R about 2 months ago. Before I had a SLP catted and it still smelt pretty rich....
Also the guy at AutoZone said it was the driver side front. He did not seem to sure of himself... So its the Passenger?

Yes, bank 1 is the side with #1 on it.... Therefore the passenger side.


Anyway, it will smell a bit rich w/o cats. Your car will tell you if its too much by throwing lean or rich codes.

Thank you! Any recommendations on what to do though for running a bit rich. It's not bad enough to trip codes but it is much worse than our other two GT's.

You can dyno tune it. It could run a bit rich stock. Get an handheld like an sct or predator and tune away. That way you can ensure your a/fs are safe.....
