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
