i replaced my o2 sensor to solve a problem with passing emissions this worked for 2 months and then the check engine light came on again. A seperate code different from the first one(heater circuit bank1 one sensor 2) p0141. I replaced the catyltic converter as a mechanic suggested after this but the engine light persists with the same code. PLease help
