In the service manual/microfiche-pdf, there is a statement that the injectors for PT and ABH are not interchangeable.

Does anyone know-
Is this an electrical characteristics issue? or simply one of flow?

It seems that the black car may be not delivering any fuel on one cylinder. i'm a little lacking in test kit at present, but hoping Output tests will confirm. I am thinking about spares. The silver car is using the PT injectors on the PT loom, at present. I have the ABH injectors kicking around spare at present.

thoughts, bitte.
