That was the only injector like that. The rest were clean in that area, except for the tip were is sprays,a cpl of them were Carboned up so bad I don't know how it was spraying.

Would the broken spring allow fuel to be dumped in all the time? Or would it make it not dump enough?

Thanks

The weak spring would throw off the injection timing for that cylinder and cause fuel quantity to change, especially if someone tried to adjust the injector with that spring like that.
