I only have one o2 sensor... I think i'm gonna reset my PCM by pulling the battery off.

I am currently using AC Delcos. Damn good Plugs. I had champions before and they were ok but not the best. Stay away from Bosch. I had put the Platinum +2'* in when I bought my car and after a week my engine started missing like crazy, so I changed them again to AC Delcos and never had that problem since. My Boschs were burned up after only 3 weeks of use. In my Caravan I had it stalling and missing like the engine was going. So when I traded it for the Bonneville my mom changed the plugs in the van and it ran like new since. I has a new set of +2'* in that van and they were burned after only 6 month to the point the engine didn't want to run. So stay away from Bosch
