99 24 valve diesel surging
Hello everyone hope all is going to have a good halloween and thnx giving
I have a 99 dodge 24 valve and recently replaced the inj pump and lift pump because the truck was surging. It is really bad between 40 and 60 mph but does do it a little bit sometimes at 70 mph. The dealer ship replaced the inj and lift pump after troubleshooting it with diagnostic equip the first time. They told me they were 100% positive that would fix it. It has only been 1000 miles and the problem is back. Does anyone have any ideas what could be causing this? My gut says electrical or transmission not fuel but this is my first diesel.
