SES light comes on when i coast.
here'* a tough one. i am driving around and when i let off the throttle, after 1 second, the Service Engine Soon light comes on. when i apply more throttle, the SES light goes off. it has been doing this for a while. so i went to school and ran the codes:
code 56 QDM (Quad Driver Module) #2
now, i have no idea what a Quad Driver Module is or how to fix it. My car drives fine other than the light coming on. so my auto teacher told me: "If it doesn't clunk out or idle ruff...just leave it."
yes, my auto teacher is a moron.

Hmmm. This problem sounds familiar. Does your supercharger boost not go very high?
Do you need a new boost control solenoid? See here:

Those solenoids are about the easiest thing to replace in the world. My mom was visiting me with her '95 Park Ave Ultra doing the same thing as yours. The code said that'* what it was, bought it for $21, took 2 minutes to put it on, saved her $225 quoted by the dealer, and I looked like a genius.
