The 2.4 does not use a maf. The tune is speed density, do one isn't needed. Mainly goes off throttle position and manifold vacuum. The maf system uses actual air flow.
Maf sensor
Thanks for your replay it help me a lot, this is my problem.
My car every time i stop at a light, starts to chake a lot and some times it stop running. The computer code give this number p0134.
This codes tells my that the oxigen sensor bank 1 is bad or fuel presure is high or low check fuel pump.
I did both, change the fuel pump and change the oxigen sensor.
And still does the same thing stops running when a stop at a light or stop sign.
In autozone the sales person told me to clean the maf sensor.
So i look in my car and no maf sensor only the rubber housing and the enclosure where the maf sensor should go. Thats wy i ask for help. But still the problem exist. This are the new error codes that
exist in my car p0300, p0452 and p0134 again.
Can some help me . :d

Did you do any testing before replacing parts? No mention of fuel pump with regard to P0134, did you check fuel pressure? Did you check whether the O2 sensor has current going to it? http://www.obd-codes.com/p0134
The P0452 is an EVAP pressure sensor issue but is not causing your shake.http://engine-codes.com/p0452_pontiac.html
The P0300 has many causes and you have to test each one before replacing anything

The "Coil Mounting Bracket" aka distributor cap could be the problem.
