It isn't a thorough test either!
This thread is about electrical testing of injectors. I own an 87 vette, it has 239k miles on it, I have driven it every day since 1989 when I bought it. The original injectors had problems early on and were replaced and never checked again and the engine runs perfectly. From this experience, I make the assumtion that well designed injectors don't need cleaning every few years. Maybe, I'm just plain lucky too,...or....driving it everyday keeps the injectors clean.

If you don't check, you don't know. My engine ran perfectly too. Jon found some issues including a collapsed filter basket. So either he was making it all up or the spray test did find some volume differences. Yet they all ran perfectly too. Why? Injectors don't suddenly get dirty and run badly. It is so gradual it is hard to notice.
