2007 GMC Sierra 2500 HD Classic SLT 6.6L Excessive Emissions
Posted to GM Driveability on 9/15/2017 14 Replies

Hey everyone, this might sound like a rant... but here we go:

This truck is giving me a run for my money... It smokes excessively from the tailpipe, with no change no matter what I do. It is grey smoke, raw fuel.

My first look at the truck I check fuel trims...
