So my Lexus is now a Gross Polluter...
I recently had to get my LS400 smogged (CA) and it came back as a gross polluter.
The engine light also came on during the test, and had the codes for the rear oxygen sensors and a valve in the transmission.
I have replaced the oxygen sensors, PCV valve and I cleaned EGR Vacuum Modulator Filter (as shown by LexLS! Thank you!). I will be soon replacing the spark plugs, wires, caps and rotor's.
Is there anything else I might do, look into, in order for it to pass the next test?
Thank you for any input.

The two rear sensors were Denso and a direct fit, the two front sensors were universal Bosch. I needed to get the front's changed the same day, so I went with the universals.
After reading horror stories about Bosch I am kind of nervous, but time will tell. They were a piece of cake to change.
