I have a really bad problem with my 96 Impala SS. It loves to kill 02's. I go through 4-5 pairs a year. I knows its due to heavy n20 use (1-2 bottles a week) and race gas. Now my question is what does the PCM do when it sees the o2 has started to react slower or die all together? I assume it adds fuel?


Any one know?

I also use Delco 02's has anyone had any luck with other brands?

do you get a lean code when they die. I have a lean code that comes and goes and cannot figure it out?

Race gas kills o2 sensors big time .Plugs them up with lead.Turbo buick guys were useing denso sensors with good sucess.

You get "slow response" codes and the 02's start to hang at 445mv.

Maybe do a search on 'denso' and try those. Folks imported info from Turbobuick.com that says that they will last a lot longer even with the usage of C16.
