working on 06 duramax, truck came in running rough, diesel knock. check codes it has a p0301,p0671,p0677 and p0116. coolant temp sensor appears to be registering properly. check balance rates and this is what I've got.
Cylinder 1 fluctuates around 1.5-2.4, cylinder's 2,3,4,5,7 all registering -4.02 and do not fluctuate. cylinder 6 and 8 registering -11.98 and stuck there
any ideas out there where to start? truck has 315,000 on original injectors so its possible there bad but the balance seem very strange.
