Geoff,

Check the following not necessarily in this order:

Ignition timing and valve setting
Fuel pressures (control and system, both cold and warm)
Unmetered air
deceleration valve opening pressure
exhaust leak (if any)

Check with Warren because he has one of the best running SC's with an incredible mileage better than my Subaru Outback Sport '06. We drove from Columbus, Ohio to Hershey without refilling his gas tank!!!!! Keep us posted.

Tony
