tech question gang,,my wife's been driving my truck l8ly,and she brought it to my attention,that at start up the trucks sounds like it sucking air,just really loudly,and does it till i guess the idle normals down i guess. i dont have my front 02,and im guessing this is the culprit,but does this sound normal to you guys?and would just throwing an 02 fix it?
Truck making loud sucking air noise at startup, is the O2 sensor the issue?

Your idle air controle could be the cause... It controls the idle by allowing air to sneak past the throttle body via Plunger (IAC) If its not opening enough it could cause a SUCKING noise.
I do know my truck has the "SUCKING" noise I think its more from the aftermarket intake then anything else.
Are there any codes to go along with it?
