Where are they now? An old build returns with a problem.

It has been a couple years since I finished the rebuild on this once rust-free GMC Sierra. It is back now with a check engine light. Is it something I did or is it just a GM truck? Since it is here, we can take a look at the repairs and see how they are holding up to the Illinois winters. I'll show you how to diagnose and repair this common failure.
