O2 codes usually take longer than that to appear. Chances are good that they got burned on the headers.

 

i checked to see if any o2 wires got burned on the headers and i found nothing. However, I did find a bad check valve on the bank 2 A.I.R tube off the headers, but that is not the problem. I'm working on finding an obd1 computer since everyone thinks it is just the o2 sensor, and I will program them out and see if she runs any better. thanks for the help, everyone.
