Check seal around IAC and all vacuum hoses. Spray carb cleaner around base of IAC if engine revs up replace gasket or vacuum hose may have come off.

I have explored this problem for a good long while & found, one should turn on the ignition & wate for all the sensor & indicator lights to go off befor befor starting engine, when the sucking sound begins turn ignition off & repete the steps again. Do this every time for about a month & the sucking noise will learn to stop. Still I continue to wate for indicator light to of off befor start up.
I am not 100% sure but I have the same problem. After reading some other forums I found that unplugging my upstream o2 sensor stopped my car from sucking huge amounts of air and bad idle. Waiting on new upstream o2 sensor now. I also read to go with NTK sensor because it’s OEM.
