Ported EGR System

  1. Check vacuum lines for correct routing. Warm engine to operating temperature. Some models with EGR delay timers must operate at least 1-2 minutes for EGR to function.
  2. While watching EGR pintle, abruptly accelerate engine to 2000-3000 RPM. EGR pintle should open at least 1/8". If EGR pintle does not move, check for cracked, leaking, disconnected or plugged vacuum hose. Verify correct vacuum hose routing.
  3. Connect a hand-held vacuum pump to EGR valve. Idle engine and gradually apply a minimum of 10 in. Hg. EGR valve stem should move and engine speed should drop at least 150 RPM.
