Answers :

Sounds like you have a vacuum leak, check all the vacuum hoses and replace any broken or kinked ones, also check around the intake manifold gasket for leaks. any air leaks after the air flow meter creates 'un-metered' air which inturn will make the car run rough and stall, hope this helps
Mine did this, it was the mass air flow sensor. $140 at autozone, 2 tamper proof torque screws and a plug. Dealer tried to charge me $430 for this repair.
