@oldguy , Rod, Bad plug wire if equipped perhaps. I find engine starter aerosol works better for locating vacuum leaks, perhaps try it(especially at the base of injector). If you can tap on the the injector body with a wrench when engine running, to see if you notice a change in the way engine runs. If change in engine, the injector is possibly partially clogged, causing miss. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
