FT is right. You will throw a code. Until you can afford either a tune or sims you can unplug them and secure them. The rear o2s just tell computer if the cats are working properly.

When the PCM detects an emissions failure it can influence the A/F mixture to help try and protect the motor. That might be causing the mixture to go really rich. Do you still have the front O2 sensors installed in the headers?

well that throws out the ceramic idea. ermmm ok im out of ideas for the moment.
actually no im not. if you still have your rear 02's, replace your fronts with the rea. they are the same, so if by chance the front are just shot, the rears should rule out that probability.
