I cleaned the injectors on my 2003 a few years ago using the same method. There were 4 holes in each injector. Each injector sprayed a flared V pattern as you describe.Does anyone know what this pattern should look like?
Cleaning mine with a reduced hose/carb cleaner and a 9v battery for power and I get a strong V pattern on both injectors. A flared vee.
Is it supposed to be a circle?
That is how mine looked and I remember having the same concern. I believe I asked on here if it was right but no one seemed to be certain. I'm still running them. Wish I could be of more help.My spray pattern looks like the picture, strong and steady in a widening or flared V. Which seems odd, given the four hole pattern.
