    Don't. The computer reads the O2's to see how much fuel to add. Without them, you would stay open loop, get shitty performance, bad milage, and and one upset computer. It would not do anything good for you. Why remove them? They are the major source of feedback on the current running conditions of your engine.

    Buy O2 sims if you want to remove the O2 sensors. I did this about a year ago no problems or codes.

    You only removed the rears, not the front sensors. The rear sensors are just to verify that the cats are working. If you added sims for all four O2's, you would never go close loop.

    like everyone has stated.......leave the fronts unless you can tune for them not being there. The rears you'll just throw a code but won't effect the cars performance.

    You don't need o2 sims. They are a waist of time money and effort. If you are looking at doing long tube headers with NO cats and an off road Y you would need a tune to correct for the free flow exhaust. Car would run lean at WOT and Rich at Idle. When you have a tune done they can delete the rear O2's and you will not have CEL or running problems but the fronts HAVE to stay. They let the pcm know how the engine is running. The rears are what we like to call tattle tales. All they can do is throw a CEL. They have no affect on mixture, timing, or anything else. Like someone said earlier, they are a warning to let a tech know weather the cats are functioning correctly.
