I have replaced the o2 sensor on the drivers side of the exhaust. Have I replaced the wrong sensor? I am willing to attempt to replace the o2 sensor on the passenger side if this will correct the problem. I get a code reading of "slow response" even tho I replaced the drivers side o2 sensor.

Do you
have the same problem?
