LB7: Problems after injector replacement

LB7: Problems after injector replacement
The check engine light was not on. It idled just fine before the injectors were replaced. I’m going to take my scan tool tomorrow and see what I can figure out as far as any codes, and balance rates. Didn’t have time this afternoon. -

LB7: Problems after injector replacement
New guy from NC! Help! What’s up guys? I’m brand new to the site and Duramax’s as well. I’ve always wanted one. I recently bought an 02 2500hd, LB7. I bought it with bad injectors. The crankcase was full of fuel. I drained it and put fresh oil in, just to be able to run it and make sure it was...
