2005 V6 AVALON intake noise

the engine in the intake area just behind the MAF makes a sucking sound when you suddenly move the accel to throttle by 1/3 of the way..

If you slowly move the throttle no noise...sounds like a vac leak at the intake mounting surface...

40,ooomi.....excellant condition...no DTC's YET...

what am I in for with this issue ?

I've had an injector seal leak spray around the intake with carb cleaner if you hit an air leak the engine should smooth out.

their is nothing wrong with the idle...
It is the noise when you ''suddenly'' increase throttle from idle to 1/3...that you hear this sucking sound...

thanks for the reply...I have still not found any with this...

Have you done any maintenance new air filter moved the intake hose for anything. Look closely for a cracked intake hose or loose fitting.
