yea the one mechanic that did the revo chip install tried some software fix that they do when you install high flow cats,but that did not work... his next idea is to move the front sensors to the front of the rear cats and then i guess seal the holes in the headers...i just have not done it seems like he is just guessing and i am the one that has to pay 120.00 an hr in labor for it...and the car runs fine when the light
is on its just irratating to look at...
