I had bought some 02 sims last year and they went bad soon after I got them. I have an ory pipe and I want to put it back on. Its just that when the sims went bad, mpg's went way way down. If I just unplug the rear 02, will that hurt my mpg's.I dont want to go through 20 buxs in gas a day

It shouldn't be bad at all... I have my rears unplugged currently cause I put in my ORY last weekend. I am getting roughly the same MPG with the rears unplugged. The only bad things is that you will see an amber SES light glowing in your face...I am going to send off my tune to have the EGR and rear o2's turned off. That will eliminate the idiot light...
