Check the throttle switrcheds to make sure they are set correctly and
working.  During closed throotle with the engine being over run, (above 1300
rpm) the fuel injectors are turned off.  In fact, if you drive down a steep
enough hill long enough in the condition, you will see the engine temp drop
as the engine is pumpin air through the cylinders with no combustion.
