Hello,, I just bought my first diesel powered vehicle.. it's a 1999 Ram 2500 with the Cummins 24 valve turbo diesel. I consider myself a descent mechanic on any gas motor, but I am just starting to learn about diesels.
My question is about my truck's idle. After the motor is good and warm, most of the time it will have a "miss" at idle. It's not a lope, like from a big cam in a gas car,, but a random miss,, you can hear it and feel it as it slighty shakes the truck when it does miss. Everything else seems fine, runs good and strong.
The truck has 216,XXX miles on it, 5 spd manual, 4x4. I talked to a friend who does lots of work to diesels, he recommended that i install a new "lift" pump? I looked in my Chilton book and couldn't find anything called a lift pump, there is the injector pump and a transfer pump before that,, Can anyone tell me,, are the lift pump and the transfer pump the same thing? some people might call it one thing when somebody else calls it something else
I also plan to service the water/fuel seperator and install a new fuel filter and have changed the oil and run 2 tankfulls of fuel through it with a bottle of diesel fuel injector cleaner.
Thanks for any help
Matt
