you are incorrect madam. the 02 sesnors you are reffering to are the rear 02 sensors that just monitors the cats. and have nothing to do with how rich or lean you car runs.Originally Posted by GirlieZ
the 02 sensors your are reffering to are in the headers. those are the ones controling your a/f but only at idle. the MAF is controling your a/f when you are off idle.
