Engine Mechanical problem
1998 Ford Taurus 6 cyl Front Wheel Drive Automatic 133000 miles
I have gotten a P401 code, and it relates to a problem with the EGR valve. My questions:
1. What does the EGR system do?
2. What harm am I doing to my engine until I get this fixed?
3. How difficult is it to replace/
4. Where is it located?
