I have a MAC full exhaust on my 02 GT. My code reads bank running too lean or something to that nature. I replaced my o2 sensors about 6 months ago and now it's time for emissions on Aug 1st. What do I need to do to get my air-to-ratio corrected?

 

Please be a little more specific on what MAC products you have installed.

 

I have Mac cai, Mac lt's, Mac catted H, and Mac catback.
