The problem
ON THE INVOLVED VEHICLES, UNDER A COMBINATION OF LOW TEMPERATURE CONDITIONS AND A WARMED UP ENGINE, WATER VAPOR IN THE WARM AIR FROM THE CRANKCASE HOUSING MAY CONDENSE AND FREEZE AFTER A PERIOD OF STEADY STATE DRIVING CAUSING ICE BUILD UP AROUND THE THROTTLE PLATE. THE ICE MIGHT PREVENT THE THROTTLE PLATE FROM FULLY CLOSING WHEN THE DRIVER RELEASES THE ACCELERATOR PEDAL, CAUSING A SLOWER THAN NORMAL DECELERATION RATE AND AN INCREASE OF THE IDLE SPEED.
What owners should do
DEALER WILL REPLACE THE EXISTING THROTTLE HOUSING WITH A HEATED THROTTLE HOUSING AT NO COST TO OWNER.
