Help--EGR replaced...still have problem
I have a 2005 F350 6.0 and about a week ago it started to sound muffled/low upon start. A few days ago after starting it quit when I shifted into reverse...I waited, started again, waited 30 seconds and shifted and it was okay. Since then it has surged a few times while idling at red lights...and yesterday at bank drive-thru it wanted to quit while idling and I had to keep revving it up...went to the Ford place and they put it on the machine and said I had a bad EGR valve and they replaced it...$520 later...it was running in the bay when I got it and left...they closed right behind me.
When I left, ran a few more errands, each time I started it there was that same low muffled sound...still there...this morning, same thing, and also it is still/again idling funny...first low, then tries to surge...I called them and they said if it keeps up to bring it back in.
What else could this be? Might the EGR they put on be bad? Any other options?
I keep my truck well maintained, it is due right now for oil change and filters change but it is not overdue.
Thanks in advance for any advice and thoughts y'all can give me...
I appreciate it!
...BUT, in the meantime, I am at an airport at wee hours of Sunday night/Mon morn with internet connection waiting to get back home and my truck is sitting in the airport.
Problems when I left Thursday a.m. First, It didn't want to start, at all. Then, it ran rough to airport and idled poorly.
I don't know if it will start after sitting four/five days.
Now 2 EGR valves and they are saying if that second one didn't fix the problem, I will need a new intake. Help!!!!
