Have the fuel pressure checked,all so change the fuel filter,sound,s like the fuel pump is weak and or going bad,that should have been the first thing that the garage checked before replacing other guessing issues.

Replace fuel pump/ circuit opening "relay" $9.00 part see diagram inside fuse box under the hood. Try that first. I have a 2006 Grand Prix and it is running with lots of power going uphill now. Also see if your EGR sensor is working. Parts do wear / erode /lose its usefulness. Bye
