Thanks for the info. I put a new Denso O2 sensor on order through the local AutoZone. They can have it to me tomorrow. It cost a little more than online, of course, but I wont have to wait more than a day for shipping and I can return/warranty it at any AutoZone.

I don't normally throw money at things trying to fix them, but I think this is worth a shot. <img src="/forums/images/graemlins/cyclops.gif" alt="" />
