02 Duramax Diesel 2500 HD

[hotdog]

Guys Gals I came on this site so that maybe someone has an answer to my problem but it seems no one has. Did anyone ever have a problem like mine and had it fixed???? 02 Duramax 2500 HD runs good cold, when it warms up has no power and getting hard to start. I am thinking maybe its the injectors but I had them changed 2 years ago. Now it has a slight miss. I am trying to figure this out before changing a lot of parts. HELP

Welcome! And ain't nothing on this site that can't be figured out and fixed.
1. Who's injectors were installed 2 years ago?
2. Do you have a way to ck balance rates?
3. Are you getting full rail pressure?

Return rate test.

Sounds like the injectors are going.

Welcome.

Return on the injectors are bad. You can do the test to be sure but 99% chance that's what it is. Go with Lincoln diesel.

Sorry for not getting back so soon. Thanks for the input on where
to get injectors I took your advice and bought 20% over injectors and a fuel pressure regulator. going to change them next week. I will let you know how things turn out

May I ask why you went with 20% overs an not stock? Stock ones can get you to 600hp an I think you have to tune for the 20 overs

I went with 20% over so I could give it a little extra. tech from Lincoln diesel said I should be ok with these injectors. if I have to tune it I guess I will.
