o2 sensors

[titefyrbird]

are there 2 or three o2 sensors on a 97, how many can be removed or simmed without major probs or ecu tuning?

are people just relocating them when they install headers?

sorry if this is a repeat, but did a search and found nothing

Re: o2 sensors

I believe the 97 is the same as the 96. In which case, there are 3 o2 sensors.

Re: o2 sensors

Yeah, you have OBD-2 so you have 2 upstream (header) 02's and 1 downstream (behind the cat)

Re: o2 sensors

Re: o2 sensors

mine has 4 also, one on each of the headers, and one before and one after the cat. The one after the cat is the one you get delete.

Re: o2 sensors

Well sense were on the subject does anyone have the part numbers for the O2 sensors and is there any brands that are better than others. I think I read somewhere that Bosch were not all that great but I can't remember. If you replace one on an exhaust manifold for flagging a code should you replace the other? I plan on getting pace setter ceramic coated headers in about 2 months. Will there be a problem installingany paticular brand of 02 sensor in these? Also my 96 firebird has 4 o2 sensors.
