Default Header Help-Poor performance

I installed a set of pacesetters today. It was a job, but I got her done. Car sounds really good but doesn't run very well. It feels like it done a cylinder. I was told that even though I don't have a rear O2 provision, that I still need to plu it in and tie it up. I have done that but the car still revs slower than it did and feels like it down on power. Any suggestions? Thanks.

I did install all new plugs. After it cools off I'll check it again. Yes, it ran bad enough for me to consider that one plug it grounded. I think I can check them with a timing light. Plug to plug to verify signal.
Thanks

Also make sure that one of your plug wires didn't melt. Any codes besides the rear O2's?

No codes except the 1 O2 sensor. I would have thoought I would have seen a ramdon misfire if I had a connection but then again, when I changed out the plugs, #1 half the ground strap was gone and a portion of the porciline was cracked. I believe that was from spraying it, but that didn't even throw a code. Prior to installing the converter, the car slowed from 12.5's at 112, to 12.7 at 109. Adding the converter dropped it to 12.3's at 110, but I still believe something had went away, I believe it was that plug.

Hoping I just didn't snap all the wires back on.
