Definitely clean the IAT if you haven't for a while. Also the EGR tube (both tend to get gummed up).

Last time I got a smog, I lucked out with a guy who used to drive an NSX, so not only did he know where the engine was ("where's the dang engine!"), he knew to keep the cats hot, run the tests in lower gears, and during the mandated shut off and restart, roared the engine to at least 6K. My car passed, and he told me that the EGR airflow was barely adequate. Hope he's still there next time...

Anyone one know where or how to clean this EGR

Was able to pull the sensor and boy was I glad, after 25 years of build up, here is before and after, it's so easy to do, took me 15 min.
