What engine ? 4.3 , 4.8 , 5.3 or 6.0 l What fuel injection system ? What is the fuel pressure ? Do you know what fuel trims are ? The fuel pressure regulator's are prone to leaking to leaking on thses SPI injection system./
How to identify and repair leaking fuel pressure regulator GM CPI system...

Does it only bogg down on acceleration or all the time? If its only on acceleration you want to check for any loose vaccuum lines leading to the intake. In addition you want to check the fuel pressure at the fuel rail and make sure that the engine is getting fuel. If so check the injectors. A clogged fuel injector or one that is leaking can cause the bogging issue and the smell of raw gas.

u may have a brake booster leaking vacum when u apply the brake its useing vacum from engine see if u can hear a hissing sound when apllying brake if so thats ur problem

Have a proper engine electrics check done.only way to fix .pay money to save money,you could lose an engine.

Have you actually taken the car for a ride,
with someone from a repair shop in the car,
to experience all the issues ?

You had work done,I assume you paid for,
but nothing your having a problen with, resolved

We have thousands of people on this site alone,
with similar situations

I find it had to believe that every repair shop is
incompetant & incapable of repairing a car

use a propane tourch dont light it start the truck
open the hood
slowely move the torch arround the top of the motor
as you hit the vac leak the engine will start to speed up since it is getting propane and reg fuel
the closer you get to the leak the faster the motor will go
and wala you found the broken or disconected hose

I would check for vacume leaks in the engine area listen for air sucking like a vacume ...You can spray a small amount of throttle body cleaner on vac lines and the motor will rev up or bogg down that is a leak and need to fix all vac leaks ........If check engine light is on have your codes checked ....hope this helps

have you checked the vacum lines under the hood for cracks in the lines or a vacum leak, sounds to me its a vacum leak.

probably just your fuel filter. if that doesn't do it , get back to me.
