1999 Honda Accord 2.3 p1167

I have a 1999 Honda accord with a 2.3, has been sending a p1167 code and occasionally a p1165 and p1166. So I bought a new upstream denso sensor and the problem hasn’t been fixed. Has had lower fuel mileage and had a random stalling problem when at full stop and changing gear, if not on gas quickly the engine would come done to very low rpm and the occasional stall.
Thanks for the help.
