P0277 strange injector

Sometimes it starts great, sometimes it idles and drives fine. They it will run like crap , barely move, and blow black smoke. I have checked the wiring and it is ok. Can an injector be intermittent?


Also any opinion on Bostech injectors?

Ficm voltage is good. and I even swapped in my spare FICM.

Harness is 6 months old, and I did make sure it was ok.

I am starting to think it is more than one injector though. It will almost not move up a hill until it is hot.

and idea on the Bostech injectors?

Thanks, I know it is not the harness, so it must be the coil. I would hav e thought that the coil would not be intermittent.
