All the CIS 928s use the SAME injector but the "warmup" control pressure regulators are different close but different. And it is the control pressure regulator which is the brains of the CIS injection.

You mentioned that your pressure is right, so I'm assuming you tested cold, warm and system pressures. If the control pressures are off by just a small amount the car can run crappy. Have you adjusted the CO mixture since replacing the CIS parts? This is a must-do after replacing some of the components.
