The vehicle stalled on several occasions.
Vehicle stalled on two occasions while driving, vehicle been at dealer on two occasions, and problem has reoccurred. Feel free to provide any further information.
Car stalls when stopped, runs poorly, a/c does not cool. Shop can not fix.
When slowing down, the engine often drops to 400 rpm. This causes stalling. If the gas pedal is tapped when the idle is erratic, the idle comes back to normal, but this is very unsafe in traffic since it causes forward movement. If the gas pedal is not tapped, the car can stall out. (this is an automatic vehicle with the 5-speed tiptronic transmission).
