3.1 Chevrolet Intake Gasket?

I have a 1998 Lumina with a 3.1 ltr engine and I changed the lower intake set. Everything went back together ok, but when I start the car, it will run for a few seconds and dies. What do I look for?

    Ok have you tried to keep it running by pumping gas pedal Can U keep it running by doing that or does it start and stall no matter what you do? But assuming that you did correctly seat and seal Lower Int then it is most likely a vacumm line or leak and its sucking to much air. go back and recheck all lines hoses and seal point especially check where where lower intake meets block and where plenum meets Lower INt and check for lines hoses or wires that you may have pinched in between them and 1 thing i did one time was missed a piece of the old plenum gasket while cleaning then whe installed one spot was doubled andhad a leak took me 2 hours to figure out what i did... if u dont find problem after allt hat let me know
