Ford Five Hundred throttle body malfunction causing stalling and lack of acceleration on Ford Five Hundred

Some Ford Five Hundred owners report experiencing throttle body malfunctions that can lead to engine stalling and a lack of acceleration. Symptoms such as rough idle and rough acceleration may indicate potential issues with the throttle body. Additionally, common causes of engine stalling in the Ford Five Hundred include fuel system and ignition problems. Owners have noted that sluggish acceleration, high rev jerking, and entering Engine Fail Safe Mode can sometimes be resolved by thoroughly cleaning the throttle body, which may take approximately three hours. Furthermore, updating the PCM (ECU) to the latest revision can help ensure the throttle body blade is positioned correctly during the starting crank cycle, thus preventing engine flooding and reducing the need for excessive throttle application during startup.
