Q: try some injector cleaner you might get lucky. merry christmas to all! i have a 04 2500 cummins auto 3.73 with 25k. it has never really run up to snuff. recently the dealer found a problem with the transfer pump letting air get in the system. he replaced it with an in-tank pump and that has helped. however it still has more vibration and noise than some of the other late cummins. pulling a 12 ft flat-front cargo trailer from ne sc to pascagoula ms 70-75 mph i got 12 mpg. i am with a sc baptist disaster relief unit. on our first trip to columbia ms a v6 f150 pulled that trailer and i pulled my 22 ft gooseneck and tractor with a front loader. i got 8.8 mpg for that trip. now for the question after a minute or so warm-up i gently ease up to 55. after about 5 miles and getting up to 60-64 mph the engine starts surging kind of like 70s cars dealing with polution controls and continues for 5 to 9 miles. colder weather seems to be worse and the problem seems to be getting worse. wonder what changing the fuel filter had no effect. thanks mark31 .
