Chugging at 45-55mph?

[cjw0120]

Been having a rough start on and off and chugging at 45-54mph anyone know what could be causing this? I'm don't know very much by any means and this is my first diesel, but I believe this is a glow plug issue? Any knowledge would be greatly appreciated!

Your problem has nothing to do with glowplugs, check ficm, fuel pressure, filters, pull codes.

It would be helpful if you take the advice of others and post replies, that way we can help you figure this problem out. That is how the forums work. Generating multiple posts and not taking the advice, and not responding wil not fix your problem. I know the answers you get will not always be what you wasnt to hear.

GPs help with starting.
Fuel pressure and turbo vanes might be dirty and sticking might be the first two to check.

Certainly check your ficm, mine was bad, not firing injector 4 equally & it led to a blown engine shortly after I repaired my ficm. A ficm test is easy & a code reader is a good investment

New to the forum but been monitoring for years. Thanks to all that have posted helping out with the problems.

I had the same problem with my truck. Lower RPM in a high gear. If I eased into the fuel it would sound like a bucking noise and I would have no power. Had a buddy at a diesel shop that ran all the test. The only thing that he could see was that the EGR Valve was not up to par. I removed it and it was clogged. Some people clean it but I purchased another and replaced it myself. Very easy. Truck runs like a champ. Hope this helps.

im new to the forum and to diesels for that matter i was just looking for some help and seeing if anyone was having the same issue! the truck has also been losing power on low fuel like 1/8 of a tank. i just replaced my egr valve and still having the same issue. i dont have thousands to dump into diagnostic time so i was seeing if i could get an idea of what the issue might be to save some $ thank you to those who were helpful and not having a pissy attitude with me starting a new thread

The whole pissy attitude thing is not going to get you any help around here. South end is pretty knowledgeable about our trucks, listen to him. If you start a thread and people give you advice and you don't take it, then you can expect people to have a pissy attitude. You ask for advice, get it and use it.
