MAF readings correct or not?

Hi;

Took an OBDII to USB reader plugged in my laptop computer, Using a freeware, I did look to MAF readings. Here they are: At idle, motor hot (183F coolant), reading goes between 2.75 g/s (9.9 kg/h) & 3.0 g/s (10.8 kg/h) and at 2500 RPM, no load, between 9 g/s (32.4 kg/h) & 9.75 g/s (35.1 kg/h).

Are those readings correct?

I'm trying to resolve my small hesitation (cut) problem when suddenly hitting the gas pedal to accelerate. No CEL, no code, nothing, only a very thin cut when pressing the gas. Strange, it never happen when using the cruise control???

Thanks for the help

Thierry

1- New Beru spark plugs last may (Problem was there before the change)

2- Throttle body cleaned in May (Was not very durty compare to what I see from others)

3- New air filter in May

4- MAF cleaned. The P/N on it is 986-606-125-01

Cruise story: When cruise control is set (70 MPH) for exemple and I'm climbing a hill, the car have to accelerate to stay around the set speed. I can't feel any cut or hesitation like when I personally hit the gas pedal. Maybe it's because cruise control go smootly on gas to keep set spped? But another detail, when I drive the car, if I want to accelerate, going smooth on the gas pedal, no problem. Probelm happen only when I hit the gas brutally.

Other observation: Let say I start the car. It is already hot. On neutral, if I hit the gas pedal brutally and release it immediatly I can ear the sound of the hesitation. It is not a constant zooooom from 650 to 3500 RPM. There is a very very thin an short missfire like at the very begining (less that 1 second) and after that the normal zooooom.

This is where I am...
