So i completly reworked my exuast on my 96 XJ today. I can't really talk about the mod i did i.e. its not exactly legal. But i removed the O2 sensor from its wiring harness. I guess my question is will it effect my engine in a bad way? I know my gas mileage might suffer and it will affect my fuel mixture. I just wanna make sure im not going to damage anything
