i recently installed a catless true dual system and removed the o2 sensors. I have a chip programmed for the deletion of the back sensors. I installed the sensors that go infront the cats and now the car is running hot on very hot days with the ac on. It doesnt overheat on cool days. I am wondering if maybe these sensors are the culprit of my troubles. Or it is just coincidence that now right after I did this mod my engine is running hot and there is something else that is wrong.
