p0153

I have a p0153 code and checked for misfires, fuel pressure all OK. O2 values are closed loop short term bank 1 -2.34%
long term bank 1 7.03

short term bank 2 0.00%
long term bank 2 0.78%

Am I looking at a bad o2 sensor and is (p0153 circuit slow response) located upstream passengers side
thank you

Year? How old are your sensors? 80-100k's can loose speed & accuracy. Remove & douche w/ MAF or Electronic Contact Cleaner usually improves function on sensors especially w/ less miles on em.
