* Rough Idle: The SRIM valve controls the air intake path length, switching between short and long runners depending on engine RPM. A malfunctioning valve can cause it to get stuck in one position, leading to a rough idle, especially noticeable at low RPM.
* Hesitation/Stuttering: Similar to the rough idle, the inability to seamlessly switch between the short and long runners can result in hesitation or stuttering during acceleration. The engine might feel like it's stumbling or lacking power.
* Reduced Power: If the valve is stuck in a sub-optimal position, the engine's performance will be significantly hampered, resulting in noticeable loss of power.
* Check Engine Light (CEL): A diagnostic trouble code (DTC) related to the SRIM valve or the intake manifold system will likely illuminate the check engine light. This code can help mechanics pinpoint the problem.
* Poor Fuel Economy: The inefficient intake system caused by a faulty valve can lead to reduced fuel efficiency.
* Possible Misfires: In extreme cases, a completely malfunctioning system can lead to misfires, further damaging the engine if left unaddressed.
In short, a bad short runner valve disrupts the optimal airflow into the engine, leading to a cascade of performance and drivability issues. It's crucial to have it diagnosed and repaired to prevent further damage and restore the Charger's proper function.
