Default Strange sucking sound coming from air intake area
My engine has been running very rough (hard to start etc.).

I have noticed an almost vacuum sound is coming from my RX-4750 air filter.

Could my MAF sensor be going out?

Any help would be appreciated. Thanks.

With that intake setup, it should sound like that. Particularly at cold idle. What you're hearing is the air sneaking through the IAC passage. Totally normal.
