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.

and

Then clear the codes.

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

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

should be at about 50 psi

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