Here is a cheap way to turn off the 2nd O2 cel....

I put a hole through my stock and I got a 2nd O2 cel. It did same thing as you; turn off after reseting but come back on a day or so later.

I did this and still no CEL after a month or so.. And it only cost 3-5 dollars.

This works on the ecos? I have been trying to figure this out for the better part of a year.
I am going to autozone today!!!
