Possible Symptoms:

  • Illuminated Check Engine Light

  • Decreased engine performance or power

  • Rough idling or stalling

  • Poor fuel efficiency

  • Increased emissions

  • Potential misfires or engine hesitation

Possible Causes:

  • Malfunctioning air assisted injector

  • Clogged or dirty air assisted injector

  • Open or short circuit in the air assisted injector circuit

  • Faulty engine control module (ECM)

Related Parts:

  • Air Assisted Injector: Controls the amount of air passing into the injectors. Problems lead to poor fuel economy

Possible Solutions:

  • Inspect and test the air assisted injector for proper operation

  • Clean or replace the air assisted injector if it is clogged or dirty

  • Check the wiring and connectors in the air assisted injector circuit for any signs of damage or loose connections
