Hey Ahmad Malalha,

This is a classic MAF sensor problem, I would try cleaning it first and then replace it if the problem continues.

Here are some guide to help you out.

Then clear the codes.

If this does not work I would check the fuel pump for low pressure here is a guide to help

should be at about 50 psi

Please let us know what you find. We are interested to see what it is.
