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.
