Made a Appointment at shop to have my balance rates checked for this year and have them shutoff each injector to figure out which one has fuel knock, I can’t tell which one it is when I use my stethoscope, is there any other tests on a Tech 2 that I should have them due at same time...
Well now I finally got my IP changed and adjusted and it runs nearly perfect [emoji16]. Next step will be injectors and in here lies my question:
I got hold of 8 original Acdelco brand new injectors (military surplus), but as I can see, they are for a n/a 6.5 (they have a blue ring). As I...
Current known Issues
1)Black smoke coming out of Tail pipe
2) Using Edge CTS3 im not getting a reading for one of my injector rates (bottom right on the cluster)
3) Terrible throttle response
4) bad gas Milage
5) randomly getting a low oil pressure warning
Im going to go ahead and guess...
1982 Suburban, NA
two weeks ago took it on a roughly 100 mile round trip excursion to get everything churned and assess any issues before I take it on a slightly longer trip with a small load (old camper weighing in at about 2200)
We pulled the camper out of storage with it and the engine...
So just picked up a 95' 3500 dually. New to the 6.5. Did an oil and fuel filter change and relocated the pmd to the bumper. I tried to bleed the new fuel filter by cracking it and cranking the motor, no fuel ever came out but the truck fired up so I closed the bleeder and just...
Having an issue with my 03 LB7.
Replaced injectors 2500 miles ago. Trucks been running great until I hooked onto the two car enclosed trailer and drove 30 miles north to race. On the return trip I looked back and could no longer see the trailer or any vehicles behind me. I slowed down and got...
Here is the video of me doing balance rates. My fuel rate is 6. From the thread below looks like I should add 2 adjustment to all of these.
Since it should be 8 on the fuel rate and I have 6 I need to add 2 to my...
Ive been working on an 03 LB7 w/140k miles on it. Egr delete and after market oil cooled fleece turbo installed before I got it. Had all the signs of blown head gaskets so tore it apart and replaced them with arp head studs. Had heads resurfaced and replaced all o rings and gaskets associated...
Hoping for some quick help on this. Our 2002 Duramax is throwing P0202. I see on the LLY Duramax this is an easy fix. I cannot find any detail on fixing this on the LB7.
Is there a fix as easy as on the LLY?
If so, where do I find the correct wiring harness for injector 2?
4000 Kms and the check engine light comes on. Diagnostic says the #8 injector needs to be replaced and 2 others are questionable.
Coincidentally met another guy with the same truck whose CE light also just came on. Diagnostics say his #3 injector is bad with 9000 Kms!
I have a 07 LBZ that is throwing a code for low fuel rail pressure. It only does it when ambient temp is over 90’F and I’m towing at highway speeds.
I already replaced the fuel rail relief valve and the fuel filter and now I’m suspecting one or more injectors may be bad. I have noticed a...
