If the injectors leak they can cause premature destruction of the catalytic converter, rough starting (due to fuel sitting in the cylinder, fuel getting into your oil. Not the end of the world, but also not enjoyable.

The tune is a few months old. The leaky injector existed before that. I just cleaned the MAP sensor, had some oily residue on it. We'll see what happens. As far as the fuel getting into the crankcase, that one scares me the most.
