Most likely the problem is incorrect minimum airflow through the throttle body, this can be cleaned with the proper chemicals to remove the carbon buildup from the throttle plate in doing so the vehicle should stop stalling . please rate my service a 3 or above ,if for some reason you can not, please ask me another question ,I will continue to answer your questions even after you rate my service until you are satisfied with my answers.

I cleaned the throttle body and I'm still having the same problem with the car cutting off.

If you have access to a live data scanner and can access the PID for the TPS sensor integral in the throttle body, you can verify the tps signal is dropping out under acceleration, or you can just replace the throttle body and solve your problem.
