The original code was p0130 which was for a bad oxygen sensor.... so I replaced both sensors. Now I'm getting 2 new codes that were not part of the original reading..... p2a00 and p1172. Please tell me what is gong on. Thanks!!!!

As far as i can tell p1172 has to do with air/fuel metering.  MAP or MAF sensor could be bad.  Have you deleted the old codes after replacing o2 sensors?
