Running rich?

[Water Warrior 2]

Carb cleaners and injector cleaners are usually petroleum distillates of some sort and probably have many common properties. I don't imagine there is too much of a difference in many cases. Unless they are a high dollar special formula made exclusively for a carb or injector there is likely no harm done. I don't know for sure but I'm pretty sure both are mostly cleaners with the injector fluid possibly having a lubrication additive for the injectors.
