Have you checked your connectors on the injectors? Or maybe the PTU? I had the same issue and found the connectors had a lot of corrosion. Cleaned the up with a pick set and electric motor cleaner, then put some dielectric grease on after.

It may be bad injectors...O-rings tend to go bad after awhile..Relatively easy fix. Z32's are notorious for having injector problems. I agree with daxnismo on the injector ends. I would check those first, and if any or some or bad it's not hard to install new connectors.
