Thread: Injector Issues

    Default Injector Issues

    So I'll start this off with the shortened version. Car broke last June, left E85 in it till Spring drained cleaned injectors and fired up ran perfect. One day a little hesitation off idle the ran for crap next. Pulled injectors, cleaned again with carb cleaner can, and light bump on 12V all looked good nice pattern, etc. Put back on, ran for crap. Put my old smaller injectors on and runs like new. They all check the same Ohm 2.2 they look good on a 12V bench test, bump with a can of carb cleaner, but obviously one or more doesn't work correctly how do you tell if one is bad? I cleaned and inspected all of the fuel system, swapped ECU changed plugs, verified spark and cam signal, etc., and for sure it was the injectors. Thanks, Russ

    I think you answered your own question. Have your injectors flowed or replace them.

    I was thinking the same thing.
    May God's grace bless you in the Lord Jesus Christ.

    I'm replacing them. I was just curious if there was another way to test them other than sending them out.
