LIMP MODE!!!
 

my truck keeps goin in to limp mode from what i hear... she says its running right and it is 20+ degrees out... but i had her dump diesel 911 in it and it cleared up for awhile but it still keeps goin into limp mode??? all i can think is the fuel filter... but its hard to tell without looking at the truck... IM HOPING AND PRAYING ITS NOT THE INJECTORS!!!!!! :madd:

Ahhhh ummm take the truck back....... Your sure shes not hammering on it? :humm:

she swears up and down she babies it... i turned the chip off and she says she dont know how to turn it on but...:humm:

It's not the injectors, :humm: well does it feel like it's running on half the engine?? Sound like a powerstroke?? could be the # 2 or 7 injector connector.

Check engine light?? Fuel filter will cure most problems, but it could be a connector......:humm: wait a minute, arn't you the one being used?? :ph: Your truck just needs a MAN to drive it, not a wuuuuuusssssspppuuuuuusssss......... :w2: :tttt:

idk what it sounds like she said it sounds :":normal:": :ouch: and i did have the :":powerstroke:": issue already and i put in a brand new injector harrness... (made me sick to my stomach hearing my truck sound like a powerstroke :tttt:)

i told her to limp it back home so im praying that its nothing major :humm:

and to that last comment :fu2:

we had a truck in the shop last week that kept goin in limp mode. and a fuel filter fixed the problem. i havent seen many problems with injectors in the lly

its surging at idel from 675-700 :humm:

You can tell a difference in 25rpm? Mines always all over the place lol

could be gellin

i am 99% sure it is the fuel filter or the fuel/water seperator sensor thingy... i should have it fixed by tomorrow afternoon I HOPE

Gonna keep it and drive it now? :w2:

ya for tomorrow at least... i pick my new toy up at one:U::rocking:

:lol88: Gotta get that knife in there a little deeper.. :tttt:

Easy first, put a fuel filter on it and see what happens.

my lly did the same thing as what ur sayin and it ended up my fuel water seperater sensor was screwed up

I had the same problem with my 2004.5 Duramax. Mine was the wiring harness going to the injectors. It has happened twice now. Its a poor design because the wires get hot and then fail. Just my two cents!!

was it the #5 and 7 injector wire harness?

C5500 with same issue
 

Just had a GMC C5500 here in the shop with same issue. Owner had changed filters numerous times. Claimed it fixed the problem each time. Finally brought it in to us and I found it had set codes P0202 and P2149. GM has a bulletin (06-05-04-47C) out on this issue. Injector harness is not properly supported at #2 and #7. Use kit number 98017958 to repair injector wire ends on cylinders #2 and #7. Kit also has two support brackets that gets installed to support the harness at #2 and #7.:tu:
