Description

The IMRC for Bank 1 is stuck in the open position. This affects low-RPM torque and fuel economy as the manifold runners are optimized for high-RPM airflow.

Symptoms

  • Check Engine Light
  • Reduced low-RPM torque
  • Poor fuel economy
  • Slightly rough idle

Common Causes

  • Stuck IMRC actuator Bank 1
  • Broken actuator rod or linkage
  • Vacuum leak to actuator
  • Failed IMRC solenoid

Diagnostic Steps

  1. Inspect IMRC actuator Bank 1
  2. Check linkage and actuator rods
  3. Test vacuum supply
  4. Test IMRC solenoid operation

Repair Notes

Replace IMRC actuator if stuck. Repair linkage. Fix vacuum supply.
