Just got it back from the dealer with 2 new injectors and a new lift pump a week or so ago. When I'm at idle or thereabouts it shakes and shudders and kind of feels like it's missing or something. BTW it's an '03 2500 with the 250hp motor.
I took it in yesterday at 99978 miles and had them make a ticket on it still under warranty even though I won't be able to drop it off 'till next week.
Anyone have any idea what the problem is? If there's a chance it's something simple I would rather just fix it myself instead of screwing around with the dealer. If it's more injectors or the CP3 pump then they can definately have it :-D (Just replaced 2 injectors on another 03 1 ton and they're $400 a pop )

 

My harmonic balancer seperated and caused my truck to shake its butt off at idle. If its missing what cylinder does it sound like is missing try taking a temp of each cylinder the cold on isnt firing correct. Dodge can hook up their dodge tool and test each idividual injector while truck is running have had them do it to mine to make sure we got my injector problem fixed.
