I have a 2004 dodge cummins that has started to miss at about 1500 rpms. The dealership just put a new set of injectors in it and that is when it started the missing. It is most noticeable when under a load pulling the trailer. Any suggestions

 

If the dealership just put them in, I'd take it back and get them to fix it.

 

No doubt, if they just put them in then it is their problem to get it fixed, and don't let them get away with the old stand by excuse that they could not duplicate the customer complaint either, if they try that then take them for a ride and show them as if they had the mind of a five year old!!!

Good luck!

 

Problem was found to be in the cruise control module. Module was bad they replaced it and seems to be fine now
