Default RPM/IDLING Sputtering

Here's what happening,when i start my ride,the rpm is below 1000 rpm when idling .When you tap on the gas or rev the motor, it sputter ( rpm will not move because of the sputtering).You have to rev the motor up about 4 or 5 time for it to snap out of this sputtering idling .Another situation is when the ride again is idling below 1000 rpm and when you put the ride in (Drive) the car barely move (or not) because of the sputtering. When you want to take off,you have to press on the gas off and on before it will snap out this sputtering mode again,After all this sputtering,the ride will take off like a rocket with no problem Spark Plugs & Wires are all new.

What car is this?
Could be fuel filter, air filter, 02 sensors
Try to get it somewhere and have it scanned to see what codes there may be
