iId suggest check the fuel pressure and clean the throttle body. If the fuel filter hasn't been replaced in recent memory, then it may be a good idea to replace it, I'm big on having a clear fuel filter when diagnosing fuel systems or stalling problems. FYI: A diagnostic code specifying a fault in a system does not always mean the specific part needs replacement. There could be something else wrong affecting that system. Don't jump to conclusions based on the name of a diagnostic code. It just points you in the direction of the diagnostic approach you're going to take.

Better bring it in and let us diagnose it, sounds like throttle body or an internal emissions part, is the Check Engine Light on? or has it been on?
