Rear O2 sensors And Idling Problems Would the removal of the rear O2 sensors cause my car to not idle? The rpm's hardly go up and popping noise comes out of the exhaust. By the way this happened after I finished installing heads on my car and the damn xpipe. Any help would be grealty appreciated!!

Re: Rear O2 sensors And Idling Problems I had no rear O2s for a while and it ran perfect. As far as I know, rear O2s don't really do much of anything other than checking that the cats work.
You plugged up the holes, or don't even have any provisions at all?

Re: Rear O2 sensors And Idling Problems I had the same problem with the new cam, the headers and the off-road pipes before I installed the rear O2 simms. Sounds like your car is running really rich and has no back pressure in the exhaust. Once I installed the simms and the Borla plate, it idles much better and isn't running as rich.
