check engine light came on, p0401 egr problem. replaced the valve. cleared code, light came on 20 mins later. Any ideas on why it could be surging... I live in AZ its getting hot but it never did this before.
you replaced the wrong part. a common problem with this code is the D.P.F.E. SENSOR. ford has revised this sensor due to so much trouble with the old ones. i would get this part from ford so you know you are getting the revised part
