Recently, my TBI 355 has been running like complete crap, ever since i got it in Spring of 2011. She was shaking bad at idle and getting atrocious mileage. So i asked my mechanic (my best-friend's dad) and he suggested a vacuum leak. Turns out the EGR hose was cracked OPEN and leaking the gas vapors out, while sucking TONS of air in, causing the truck to burn TONS more fuel to keep the mixture correct. We replaced the hose, and hose-clamped it. I now have 72 miles on the trip meter and STILL have a full tank, and she runs at a much lower RPM, no studdering, and sooo smooth at idle and accelerating.
Here is what I'm talking about, for whoever doesn't know, it's right under the front of the TBI unit. I'm not sure where it is on the Vortec engines, so i just mentioned TBIs in the title.

Also, this one was cracked to hell too, its on the passenger-side valve cover:
