I do it at least once a year on all cars that I own. I use a water soluble
bio-degradable degreaser (as compared to solvent based), available at
K-mart, etc and spray the greasy areas of the engine. Wait for a few minutes
for it to soak and maybe brush really dirty, greasy areas (old oil leaks,
etc) and then hose the engine down with a nozzle attached to the garden hose.
Take care to not spray water directly into the air intake or the distributor.
You can use plastic shrink wrap around the distributor for extra protection.
Start the car up right away after the wash to dry the engine area.

The Delco CC units have a diagnostic mode where you can check the function
of these sensors and the positions of all the flaps. Check Bentley for the
procedure (its too involved to describe - not that I even remember it).
