1995 850 na

A1 1-1-4
A2 2-1-2
A3 1-4-2

I reset the codes after I read them this morning. I'm thinking that the A2 code is the one bringing up the check engine light (O2 sensor). I had both sensors replaces about 2 years ago, and did not expect one to go bad so soon.

I went to Bay 13 and checked out the instructions to replace the front...is it very hard? Is it worth it to get the Bosch sensor?

Thanks for your info...Bob
