misfire (please help)

[98z28m6]

Well i took my car into my auto tech class today to let my teacher look at it. I hooked the computer up to it and all its throwing now is a bank 2 senser 1 high voltage. So i switched the o2s around to see if it was a bad senser and it wasnt. I followed the wires up to the pcm and its covered in the black plastic stuff, and then heat wraped but it closed to the headers. It doesnt look like it melted so what else should i check.

It seems to run worse and worse everytime i drive it.

Any help at all again is very appreciated.

Clear the PCM memory by disconnecting the battery for 10-15 minutes. Unplug the o2 sensor's and drive the car then get back to me here.

I did what you said, but i only unhooked the passenger side o2 because i didnt notice you said both. But no missfire anymore . What does that mean?

Thanks for the help you dont understand how much i appreciate this!

Unhooked both and reset it again. If you get on it it does missfire a little bit, its like da daa daa da daaaaaaaa lol you know what i mean. nothing liek before though.
