Plymouth Grand Voyager engine stalls at stops and surges during deceleration, possible EGR issue on Plymouth Grand Voyager

Some Plymouth Grand Voyager owners report experiencing stalling at stops and surges during deceleration, which may be attributed to a malfunctioning EGR (Exhaust Gas Recirculation) valve. These issues can manifest as erratic idle speed and rough idling, significantly affecting engine performance. Owners have noted that a faulty EGR valve can disrupt the air-fuel ratio, leading to reduced power and fuel efficiency, as well as stalling and hesitation during acceleration. To mitigate these problems, some owners have found that cleaning or replacing the EGR valve, along with testing and replacing the engine coolant temperature sensor, can help resolve the stalling and overheating issues associated with the EGR system.
