I have a 2009 Kenworth with a C13 that shuts off as soon as i go over 25mph, turns back on itself as soon as it goes lower than 25mph if its still in gear, if i go into neutral it will completely shut off and i have to wait a few minutes before im able to turn it back on with the key. I lifted the rear differential and run it in place and it will not shut off at all, i go over 25mph easily and it will let me go at wtv speed i want and it wont shut off. When it turns off while driving there isn’t a check engine light or any code when i connect with the ET program. Anybody had this issue before and what fixed it? I really need help here, thanks in advance.
