Alright, got my Injector circuit test, also known as a NOID light.
All six give bright consistent flash every time intake stroke comes around.
Ordered a set of new injectors and expect them this week.
I wish fuel filter was not in tank so I could change it easier.
I'm thinking (Danger!) when I ran the fuel/injector cleaner thru car it broke loose some crud and plugged injectors.
Like the Z4 but wish I got to drive it more and work on it less
