Replaced catalytic converter and front oxygen sensor. Replaced rear oxygen sensor and it would not idle. Put old sensor back on and it idles and dies when warmed up.

Yes check engine light is on and the auto parts store said there were 2 codes (which he did not give me the numbers) which showed to be oxygen sensor and vacuum leak.

Vacuum leak would cause stalling and O2 sensor codes. I need to know the exact codes.
