Re: why am I stinky?

My EGR has two ports coming off of it, but only one hose. Which one do I use?

Not absolutely sure, vacuum opens the valve during warm-up and will close when the engine is at operating temperature. They should connect to a switched port somewhere, not very familiar with TBI systems.

Re: why am I stinky?

It could be your cat my k5 would do the same thing and when I took the cat off it was a whole lot better and the fact that it dumped a pound or two of soot when I turned the cat on its end. I am pretty sure the repair manual even says that a strong smell is an indicator of a cat going out but you will have to check on that one as I don't have my book around right know. But my blazer was also in bad need of a rebuild

If the engine runs rich the pellets will melt in the cat and eventually clog it. If your area requires annual emission testing it will get flagged if CO levels are too high. Worth a look, and of course you'll need to correct the rich burn before replacing the cat. Several counties in TX require emissions tests for all vehicles 2-24 years old, mine doesn't.

Just a thought.
