    Default Injector tests and cleaning

    Well for weeks I have been trying to get my capri to run better, check settings, change some parts and I just couldnt get it to run over 2500rpm. It would just lay over and the rpm's would drop. So I removed the injectors and took them to get pro cleaned from R.C. engineering (yes that R.C.) look at the before and after tests, and oh I replaced all the plugs today and they were all having signs of lean on them Attachment 129259

    Just curious, did you do an engine cylinder balance test to see which had an issue?

    How old is the fuel pump?
    My LSC was acting like that just before the pump failed.

    Makes sense that it was giving you problems

    +1 on checking the fuel pump.

    Brand new pump, this 94 motor sat for over 10 years so by looking at the results it needed them cleaned and new O rings
