possible vvt solenoid... since you have fresh packs and plugs ....assuming all AF sensors are new
also keep in in mind original codes could be fuel issues, although more related to AF sensors. you may want to run a bottle of injector cleaner, it won't hurt anything and only cost $5

I have researched the part number, and I see 2 different part numbers for the sensor:

In the meantime, I disconnected the electrical connector, cleaned both sides off with brake cleaner, blew both sides out with compressed air, and reconnected. I cleared the code with my Actron OBDII code reader and have been driving all afternoon without any more check engine lights/codes.

So even though it doesn’t throw a code immediately, the code may still come back.

the right os2 sensor is the 9009 for the bank 2 sensor 1 which is in the front of the engine is relatively easy to replace unless you strip the threads like I did.
good luck!
