Car Stalls

I just had the intake gaskets changed......and the car just randomly stalls at low RPM's when braking or coasting. The computer is not throwing a code or anythign. The "check engine" light does not come on. Whats the problem?? the Fuel pressure is fine. confused here. The Fuel pump has alot of miles on it, same with the filter, could that be the problem?

Was it stalling before the LIM gaskets were replaced? It sounds like you may have an engine vacuum leak or low vacuum. Check all the vacuum connections at the LIM, throttle body, all sensors like MAP, purge and to the braking system.
