yeah that determines your A/F reading. That is what your problem is.

you should have the front o2's conected. the front ones detemine the air fuel ratio

Its going to run like crap till you hook up the other o2... might burn your plugs up too because its running so rich.

if you had 4 hooked up before, why would you only hook one back up?

Yea hook the fronts back up. Also if your done modding your car, or atleast for a while, get a tune. A tune was the best mod I did, and you can have the shop turn the rear O2's off and you wont need O2 simulators.
