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.
