Air Pump Switchover Valve
What’s the air pump switchover valve, and how do I check it?

I also ordered 4 Bosch 15733 universal O2 sensors ($20 each from amazon warehouse - if they’re bad I’ll return them).
I also read about clearing some choked up **** in the front of the engine, but I’m not sure what that is.
Hopefully this will nuke the code. O2 sensors should get done regardless - it *will* make a difference.
