Hey guys, Im kind of new to the diesel world and i need a little help. I've done all the searching I could and I cant find what i'm looking for.... So any info would be awesome!!
I bought a used 2004 (305hp) 2500 cummins. It was all stock when I got it. It has 196000 miles on it. Don't know a hole lot about the service records. I do know it was a work truck with a service contract.. (I called the shop that did all the work and the a$$ [email protected]
told me he cant give that info out, he said "its like medical info I cant give out")!!!!!
Anyways I put 4in diamond eye turbo back exhaust on it, installed the home made big honkin air filter kit (the big cat dozer filter) and took out all the silencers and installed a EZ Edge programmer.
The truck ran and pulled my car trailer awesome!!! It was very fast for only having a few things done to it.
I now ended up getting a set of DDP 50 hp nozzles for it. I did buy them used, but the guy I got them from seemed very respectful and honest. He was even going to help me put them in. I didn't take him up on the help thinking I could handle it no problems... (i own a performance shop mainly gas engines, so i am mechanically inclined). I did get the ddp directions off line and i also got a dodge service manual from the local dodge dealer..
The first problem i noticed is when I took out the supply tubes. On the back 3 tube's nuts holding them in the head where kind of damp looking and more rusty than the front 3... When I pulled the front 3 tubes out of the head a very small amount of fuel drained out of the head (i would say it was what was left in the injector or the tube when i pulled the tub off the injector). the back 3 tubes had at least twice as much if not 3 times the amount of the front 3... I don't think it was supposed to be like that???
The second and biggest problem is after i put the injectors in the truck feels slower and like the truck is working harder to pull my car trailer. I did EVERY THING BY THE BOOK AND DDP DIRECTIONS!! I took my time and kept every thing clean. I got new copper washer and new o-rings for the transfer tubes. I looked over the tubes and the 50hp nozzles for cracks, and made sure every thing was right. I made sure the holes on the injectors was lined up to the nozzles and the hole on the injector was lined up to the transfer tube. I did every thing just like the directions said!! The truck did idle a little rough before i put the nozzles in (about the same as other people say how 3rd gens idle). After i put the 50hp nozzles in it idled perfect. It dose now smoke a little on cold start up ( i think that's because of the bigger nozzles), but goes away after a few min.
I've been driving it for a few days now and it seems to be idling a little rougher now and still low on power. I don't know what to do next... Could it be one of the pumps?? I know my truck has the up dated lift pump from dodge (i have no idea how old it is or miles). Or could it be the high psi pump?? or the nozzles are junk?? or dose it go back to the transfer tubes?? I don't have any gauges yet to help me out.. The truck also doesn't blow any smoke when to the floor.. I know it shouldn't do it a lot with only the ez edge, but i thought with the 50 hp nozzles it would have a light haze to it. I can almost say it had a bigger puff before i put the nozzles in!!! The truck has no codes. The fuel mileage seemed to stay the same as well.
if any thing rings a bell let me know.:banghead:
