General Motors used to have a real problem with carbon deposits
in combustion chambers, and sold a solution that you added to the
intake of a running engine until it stalled.  Waited overnight and
started the next morning, all carbon gone (most).
  Just use a planter mister(sprayer), and way less than a pint should
do it.  Ya wanna be sure not to hydralic the motor, and bend a rod.
  One thing to watch if your gonna run water injection full time is
condensation in the oil pan.
  Personally, not to throw water on the idea, I never saw any marked
effect at using it at cruise.   You'd think if there was much to this idea
someone years ago would have gotten it right.  Sounds like the
1950's claims of with this solution you can run your car on water.
  If you use a quality detergent gas, now a days the intake tract
carbon deposits are nothing like they use to be.
  Also watch for throttle plate icing.
  Wouldn't be surprised to have intake tract icing, and big chunks
breaking loose.

Just my two cents on things to watch for.
