I have a 1997 Mercury Sable. My service engine soon light is on I had it checked and they said my EGR Valve isnt working correctly. I have a little miss when ideling other than that I havent really noticed any other problems. How important is the Egr Valve. How hard is it to change on this car? How much do they coast? :roll:
