o2 Wires crossed in rear, stumped

[Nightlife218]

After replacing the front o2 sensor with an oem one from the parts store I was informed that the rear o2 sensor was not needed, so, instead of paying for the front oem o2 full price I had the rear warrantied out. When i was trying to tuck the cut rear o2 wires which I had left stripped on accident they all were crossed without my knowing. When I went to fire it up, the cars boost gauge read full boost and then would die. When I went under the car I realized I had crossed the wires. I then replaced the rear o2 and now it sputters until about 3500 and then it takes off but the boost gauge reads no boost Any help? rear o2 schematic would help but as added information its now throwing these codes: int air temp sensor 1 cir, temp circuit, mass air flow circuit. Please help me

I had a similar issue about a month ago.

If you don't have anyone lined up to fix it, I'd recommend Steve. He fixed mine in a very timely manner and for a very fair price.
