It is possible to have the fuel injector electrical connectors crossed for cylinders 5-7 and 6-8, which may cause an engine misfire. The engine misfire may not be detected and may happen during deceleration.

If crossed injector connectors may be a possible cause, follow the appropriate Service Information to validate the injector connector routing. (Fig. 17) If necessary, correct the injector connector routing and evaluate for proper operation.
