   I definitely noticed a difference when I got new engine (with new plugs).  I   
   have better acceleration than I had previously.

   I have always bee worried about using a power washer in the engine area due to   
   the possibility of messing up the electronics.  I guess as long as you keep   
   the spray away from the electrical parts and sensors, you are fine.   
      
   I plan to clean the throttle body and all intake hoses while I have it all off   
   the top of the motor.  I'm sure there is carbon build-up in there that needs   
   to be blasted off with carb cleaner.
