Dirty sensor in intake?

[Xproplayer]

I'm trying to investigate and do some due dilligence on a throttle oscilation issue I have, when at maintenance or light throttle between 2-3k rpm it sounds like the rpms are fluctuating like a sine wave. I have the Verus resonator delete cap so I am reverting that (just in case) and I noticed the sensor (map? maf? temp?) right after the air filter seems dirty on the leading edge, should I do anything about this?

It’s just a temp sensor, I highly doubt a little dirt will cause any problem. Might as well wipe it off though.
