Miles? Looks like a 4 02 sensors but check for leaks first. Just 2 weeks ago i had 0496 code and both primary 02 sensors code, secondary are turned off, replaced the evap purge solenoid only all codes gone.

About 150000. I guess I can start with the evap stuff. The O2 codes came after the evap was on for about a week

Exactly, fix the 2 codes sm and LG leak and the others should dissappear. Look for broken or cracked hoses, easiest was is with motor idling spray carb cleaner around all hoses and joints if the rpm fluctuates you found the leak.
