Here's what it's doing. The regular "diesel knock" that is given with the sound of every diesel motor, completely goes away when I get off the gas. And when I come to a stop at idle, the "knock" is all over the place, and shakes the entire truck. Also, the motor is stock (no tune, etc.) and is blowing black smoke out the exhaust at idle. And when I give it a little gas, it smokes the sh!t out of everything. What's going on with this thing?? I drove it from Texas to NC Friday, and it ran fine for the most part, but did throw an over boost code half way back. The code went away by itself, and the service engine light is not on right now. Whats going on??

Sounds like injectors to me, how many miles does it have on it? It could be the wiring harness for the injectors or the injectors themselves, either one is common for the LB7 trucks (2001-2004)

Yes the original warantee is 5 year/ 100,000 miles, but the LB7s get a 7 year 200,000 mile extended warantee for free.

 

Are there special resrictions to the 7 yr. 200k mile warrantee? Because the dealer that I took the truck to has verified that there is one bad injector, and they are not going to replace it for me.....unless I fork out $1200.

So I went back to the dealer today to talk to the service manager. All I have to say is.....*hole!!! He's trying to pull out everything he can to get me to pay for this. I don't understand. It's not like his dealership would pay for it, GM would. I asked to get the diagnostic in writing. He didn't want to give it to me. His reason for the problem not being associated with the special policy that would cover it....it didn't throw a code. WTF!!! It doesn't have to. The policy says it MAY throw a code. Not 'must' throw a code. And the one part that would immediately link the problem with the special policy is a fuel return flow rate test..........WHICH THEY DIDN'T DO BECAUSE IT DIDN'T THROW A CODE!!! They're suposedly doing the flow rate test now at my request, but I have a feeling the results will be BS anyway.

Always remember if a dealership gives you woe, you have every right not to give them your business. Find a dealership that takes care of you.

      Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.
