2000 Grand Caravan-Low EGR Flow Code

Check Engine light is on and the Local AutoZone pulled the code and said it was labeled as a Low EGR Flow. Do I need to replace the EGR valve or is there another alternative. The van runs fine 99% of the time. Occasionally on the first start of a cold day it will start with a miss and will stall everytime we take our foot off the gas.
