O2 Sensor question I got a check engine light today and had it scaned and it turns out I need to get a new O2 sensor for my Z28. I need the passeger side front sensor (bank 2 sensor 1). Its the one before the cat, if it even makes a difference. Now what I was wondering is if I should get a GM replacement or will an aftermarket sensor like a Bosch be an ok replacement? I could have sworn I heard around hear to only use GM sensors, but I could be way off.

Re: O2 Sensor question Bosch invented them, more or less, and
I think is still the biggest maker; the
GM one is more than likely Bosch inside.
Replace both sides. This will ensure they
are both similar in their response (though
the PCM appears to manage sides separately,
it's still best to replace them both since
as they age they do get sluggish and that's
seldom good for performance). Besides, the
incremental labor is like half an hour, once
you get it up in the air.

Re: O2 Sensor question Placement does matter. The front ones are the ones running the show. FWIW, I'd change both fronts, too! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
