how to repair insufficient EGR flow


how to repair insufficient EGR flow and make engine light go off on 2000 mercury mystique 2.5L 6cyl.? Already Tried: new EGR 


Call the Ford Dealer and ask for parts dept. Then replace the other two EGR components: the EGR Regulator and the EGR Position Sensor..I usually add the EGR as well, but you stated you already replaced it.

This will take care of the code. I say call the dealer, because it is difficult to find an exact match as the regulators are individually calibrated. Should not take you 20 minutes to replace both.
