I have a 06 Duramax with 400k on the clock..got a P0087 code and am worried its fuel injectors...I will try replacing the flexible fuel hoses but....I searched E-bay and there’s a lot of engine rebuilders that will sell a refurbished ( all new inards) for starting at $3400.
I’m thinking I want to keep this truck, a new rebuilt engine and interior is a lot less than a new truck..
