Default 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!!

I also swaped out the plugs to TR6 and had them gapped to .35. Would this have any change in the idle?

One more thing I forgot to mention, I also removed the EGR system and put restrictor plates where the valves used to go. Would this be the culprit?

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?

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.

The rear O2 sensors don't have anything to do with the way the car runs.
