before just throwing parts at it it would probably be a good idea to get it scanned for codes - they can monitor the ect with the scan tool rather than have you throw away money on a part that isn't required, could also be any number of things - ignition system, IAC, mechanical...good start is to eliminate the obvious

gm spec: key on 60-66psi for central SFI
56-62psi forthe SFI

good luck...
