In fact, I removed it and replaced it to be sure it was screwed on properly, but I am still getting the CEL. It looks like I will probably end up replacing the rear O2 sensor. I have read a thread here that I can get one for around $80 on ebay so I will check that out. Is this something that I should be able to replace myself? If I have to drop the gas tank or something else major then I will end up going to the dealer (groan). Thanks for any help in advance.

I have looked at ebay and have not seen an $80 o2 sensor...maybe someone could enlighten me.
