I have been chasing some rich codes that are preventing me from passing smog so I did a dive into the truck and found even more issues! I think I am on the right track though with searching for a vacuum leak. I smoke tested the engine and found a cracked maf housing so we are replacing that but when I was looking at the truck I found a leaking ac compressor, a broken motor mount and some small leaks.

I bet the rich condition is from the air filter being clogged, not enough air to meet the fuel being given?
