i own a 1998 cummins with the 24v. i recentley put another pump on the truck and it started to skip at idol. what could cause this?

 

did you put an injection pump or lift pump on?

If you just put an injection pump on chances are your stock lift pump crapped the bed, and you need a good aftermarket replacement. AirDog or FASS are good choices.

If you put a new lift pump on your filters might be clogged up. If you got a OEM replacement I hate to tell ya but your wasting your time with a stock lift pump they'll just keep going out.
