Thread: Fuel injectors

  1. #1

    Fuel injectors

    1989 Chrysler Lebaron GTS - 2.5 T1
    I had some spare fuel injectors ( #4418213 ) and sent them to a fuel injection place to be cleaned and tested. Over the weekend I took out and replaced the injectors with the ones I had cleaned. After starting car it had a miss. Also took out fuel injection wiring harness and cleaned, tested for resistance and retaped the harness.
    So I reinstalled the old fuel injectors ( also # 4418213) and car works fine. I even tested the cleaned injectors for resistance and they all tested good. Anybody have any idea why the cleaned and tested injectors would produce a miss ?

    P.S. Does the ohms resistance test prove a injector is good ?

    Ohm value can't verify the mechanical operation of an injector. It is possible that the injector was failed before cleaning. Did they flow test the injectors?

    Yes, they flow tested the injectors. They tested before & after cleaning.
