    It seems my '95 has an injector issue on #2 cylinder. I can pull off the connector, it still runs the same.

    Rebuilt ECU, bench tested. This is the ground for the injectors?

    Replaced all injectors, error code 27, Grounding.

    How do the others fire off?

    Is this a floating ground? Whatever does this mean?

    I disconnected the battery after starting it. I can pull off the connector while it's running, there no change to the rough idle?

    Is the Auto Start/ECU relay replacement going to help ground?

    I installed the rebuilt ECU, and I still get error code 27.

    Can it still be an injector?
