I didn't remove the upper O2 sensors when I cleared out the precats... so maybe I did damage them? The extra set of MIL eliminators are there because I thought the first set didn't work and I didn't want to remove them (solder in) so I just plugged another set in. Are you sure that those codes mean the 1st set of O2 sensors? Can they be cleaned or do you think they are just busted?
