check sign appears on dashboard and scan says it is barometric pressure sensor malfunction. Engine stalls and sometimes goes off when I want to move after being stationary in traffic. What can I do to solve the problem?

 

take the car to a technician.

 

Typically when we see that code the car needs a new ecu because the Baro sensor is in the ecu

 

This. There is no repair for the baro sensor and for some reason they seem to fail.....
