Replace O2 Sensors and still throwing codes
It's flagging the driver side pre cat o2 sensor...I have the actual code written down somewhere but cant find it, it just says it has slow response though.
It's weird though because it threw the code a while back, so I replaced it with a Bosch direct fit O2 sensor from here:

Once replaced, the light went off for 3-4 days. Then the post cat 02 sensor came up so I replaced that one as well...Then a few days after that the pre cat 02 sensor came on again so I have just been ignoring it the last few months.
It was running rough a little bit ago so I checked the codes again and it said there were misfires on the whole driver's side bank. Pulled the coil packs and saw there was some oil in there so I replaced the valve cover gaskets and since then the misfires went away, but the light for the pre cat driver side O2 sensor came on again.
Any thoughts?????
