Re: 04 f350 6.0 surges on highway
Just got back from 2nd dealer trip. The first time all checked ok and they cleaned egr valve. Sent me home and 1hr out it surges again. Next week take it back aand they test drive again but longer and it finally acts up for them then the egr valve dies. Turns out the sending unit in the egr valve that tells the comp. how open it is was intermittent. Drove 3.5 hrs home and seems to be good. Thanx to anyone who took time to read this and try to help.
