2001 Lexus IS 300 6 cyl Two Wheel Drive Automatic 104, 00 miles

i have an accelerating porblem with my car. I got the fuel injector clean and it work good for a month and then the problem came back. I got the injector rebuild and new fuel pump and fuel filter and spark plug. It feel a lil better and still lag but this time everytime I step on the gas pedal it make a sound like a strawl noise slipping on soda. Like some sucking noice for the engine, everytime I accelrate. Is that a transmisson problem?

HAVE YOUR MAF ( MASS AIRFLOW SENSOR ) CHECKED FOR CONTAMINATION ON ONE THE TWO HEATED WIRES
USUALLY THE CAR DOESN'T KNOW HOW MUCH AIR IS COMMING IN
