I'm doing this for a friend so bare with me on this. The car is a 1995 mazda protege dx 1.5 liter dohc. The code popping up is something about 1195 manufacture. Can anyone tell me what this means or what part need to be bought. THanks.

Here is what I found. You will probably need a troubleshooting manual or advice from repair shop to figue out what to repair, clean or replace.
P1195 1/1 O2 Sensor Slow During Catalyst Monitor (Chrysler, Jeep)

You can look up any code here.
