Craig,

Look for something else.

You're using four times the fuel you should be.  An exhaust leak will
affect your mixture, but not to that extent.  I've driven home with a
broken exhaust - like fully separated - and not had the mileage affected
to a noticeable extent.  Unless the dent is such that the exhaust flow
is pretty well closed off, you won't get this effect either.

Sounds like your injectors are stuck open.  That sounds like a CPU
problem.  Do you have a known good unit you can swap in?  Can you get
one?  Perhaps from another listee?
