Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Rough idle or misfire on a specific cylinder
  • Poor fuel economy
  • Check Engine light with an injector-related fault code

Installation information

Routes from the ECU to each injector location — check for secure, correctly seated connectors after installation.

Frequently asked questions

Both a bad wiring connection and a failed injector can produce the same symptom (a misfire on a specific cylinder), so a mechanic will typically test the wiring’s continuity and connection before condemning the injector itself.
