Symptoms and Conditions
Some customers may experience an intermittent or constant rough idle
with MIL illumination and DTC P0300 and/or P0401 being stored in memory.
This condition may be the result of rust accumulation on the EGR valve
shaft causing the valve stick open. A shield has been added to the
valve's body to prevent reoccurrence of this condition.
Repair Procedure
When you encounter a vehicle with this concern inspect the EGR valve
for this condition and if necessary replace the valve with the improved
part.
