Troubleshooting and Problem Solving

Common Issues After Installation

  • Check Engine Light: Common if the engine computer is not tuned to account for the removed EGR system.
  • Rough Idle: Typically caused by loose bolts, improper gasket installation, or air leaks at the block off plates.
  • Reduced Power: May occur if the plates are installed incorrectly or if there is a clog in the intake manifold from prior carbon buildup.
  • Coolant/Oil Leaks: Caused by improper gasket seating or over-tightened/under-tightened bolts.

Error Code Solutions

  • P0401: EGR Flow Insufficient - Use an engine tuner to disable the EGR system in the ECU, or check for loose block off plates.
  • P0403: EGR Circuit Malfunction - Disconnect the EGR electrical connector (if not already done) and use a tuner to clear the code.
  • P0404: EGR Position Sensor Circuit Range/Performance - Disable the EGR system via tuning, as the sensor is no longer in use with the delete kit.

How to Reset Check Engine Light After Installation

  1. Use an OBD-II scanner to connect to your vehicle’s ECU (available at auto parts stores or online).
  2. Select “Clear Codes” from the scanner menu to erase the EGR-related error codes.
  3. Disconnect the negative battery terminal for 10-15 minutes to reset the ECU (alternative if no scanner is available).
  4. Reconnect the battery, start the engine, and drive for 10-15 miles to allow the ECU to re-calibrate; if codes return, use a tuner to disable the EGR system.

What to Do If Your Vehicle Loses Power After Installation

  • Check that all bolts are tightened to the recommended torque (18-22 ft-lbs) to prevent air leaks.
  • Inspect the gasket and O-ring for proper seating; replace if damaged or misaligned.
  • Clean the intake manifold to remove any existing carbon buildup that may be restricting airflow.
  • Verify that the EGR electrical connector is disconnected (if applicable) to avoid ECU confusion.
  • Contact our support team at service@egrperformance.com for further technical assistance if issues persist.

Long-Term Maintenance Tips

  • Regular Inspection: Every 10,000 miles, inspect the block off plates, bolts, and gaskets for signs of wear, leaks, or corrosion.
  • Routine Maintenance: Every 20,000 miles, clean the block off plates and mounting surfaces to remove any dirt or debris that could cause leaks.
  • Wear Parts Replacement: Replace the Viton O-ring and graphite composite gasket every 30,000 miles or if signs of wear (cracks, brittleness) are present.
  • Hardware Check: Every 15,000 miles, check the tightness of the stainless steel bolts and retorque to 18-22 ft-lbs if necessary.
  • Storage Tips: If storing the vehicle for an extended period (3+ months), clean the block off plates and apply a light coat of anti-corrosion spray to prevent rust.
  • Warranty Reminder: Following these maintenance guidelines will keep your 1 Year Limited Warranty valid.
