Is my O2 sensor bad?

[89mulletbird]

I've been running the same O2 sensor for over 5 years, and after my last track day running low lead av-gas my O2 sensor shows between 0 - 300mV on my Scanmaster at WOT. I don't think it is running that lean because it is running OK, do you think the O2 sensor took a dump?

wouldn't hurt to change it. their only thirty bucks. when they read low they usualy have gone bad

Any preference on brands? I see Bosch sensors at the parts store for $20.

I have the same problem does alky destroy o2 sensors? WOT dips down to the low 300mV and i have no knock weird. I would just throw another one in. Let us know if it solves the problem?

Bosch works good, I used to melt the tops off of Borg Warners.
