P1004 on Chrysler by model: symptoms, diagnosis and fix
The 3.5L V6 intake manifold runner control (IMRC) valve actuator fails, causing a loss of low-end torque and a check engine light. The IMRC system varies intake runner length for optimal power across the RPM range.
Common Symptoms
- Check engine light
- Reduced low-end power
- Slight decrease in fuel economy
- Rattling from intake area
How to Fix
Replace the intake manifold runner control actuator. Some aftermarket solutions include deleting the system and pinning the runners in the open position, though this reduces low-end torque slightly.
