97 o2 sensor then P1195
I just bought my 97 LX 3 weeks ago with 120K on it. after 2 days it threw a CEL. comes back as P0420 upper o2 sensor. i had advance get me a new one. it looked different but the old was a NTK and new was a bosch. Get it installed and plugged in and within 5 feet i get another CEL. comes back as P1195. cleared code and it came back right away. pulled out new sensor and put back old one. code came on right away P1195. drove back to advanced and cleared the code. then drove 10 miles home and now code. it normalld took about 20-30 miles for the CEL with the o2 sensor to come on. they are getting me a new one. any ideas?

Thats an EGR boost sensor code. It could be a clogged hose to throttlebody/poor electrical connection/dirty egr ports or bad boost sensor. Definitely not an o2 sensor code.
I would clean the throttlebody and egr really well first.

usually, you pull two or three codes at a time. if they only found one, they didn't look hard enough. the sensors that they use generally require you to push a button to get the second code and they just don't seem to have the time for that.
this sounds like the infamous protege egr issue. it has always been a weak point on the motor.

Ok here is an update. I changed the O2 sensor. It got rid of that code. then i got the code P1195. EGR valve. i pulled the EGR off and cleaned it. unhooked the batt. and code went away. 2 days later i get a CEL again. i'm sure its the EGR again. any ideas? Plugged vac line? any ideas?
