I bought a car that had the catalytic convertor cut off. I was told that there is an o3 sensor in it and the reason it is running so badly (no power, stalling when trying to accelerate, rough idle, noticeable mis) is due to the missing o2 sensor/ catalytic convertor. There was also a Mass Air Flow Code coming up and it wouldnt start at all but i replaced it and it now starts but stalls out until it gets warm. Then when it does get warm there is no power and running rough. There are no codes coming up since i replaced the MAF sensor.
What makes this problem better or worse?
Won't start easily. stalls out when engine cold. No power and misses when warm
