Vehicle stalling when braking
 

My friend has a 2005 Mazda Tribute V6 engine and everytime he applies the brakes when approaching an intersection the RPM's drop down and the vehicle stalls. I asked him if this alsooccurs if he puts the transmission in park an he stated no. Check engine light does not come on. What could be the cause?

A bad Mass Air Flow sensor aka M.A.P. sensor can cause that....keep us posted
