'99 2.5L Runs fine, intermittent check engine light

Ironically my errors came up as secondary to P0446 error. If Aanic does not take parts, I will.
How do you know pump is running?

No issues on my end, no parts needed. Was more interested by the idea of removing unnecessary smog equipment. Any performance or other benefits? Easy to do?

There are several components involved and it is rarely the air pump that fails. If it's working, you'll hear it at cold startup.

FYI: p0446 has nothing to do with the SAI system. That's an EVAP code.

at cold startup. So maybe the sound that I think is the fan working is the air pump. Also, I have started to diagnose the EVAP problem and will go after the valve near intake and the canister. Already replaced the tank valve on canister.
Thanks Particle.
