1991 Oldsmobile silhouette starts and dies right awayd Before it did this It ran fine. I start it. push the pedal back and forth but wont gain much rpms then dies.?

my 2000 oldsmobile did this after it got an antifreeze hose behind the motor and come find out ... the mechanic accidently broke off the VACCUM hose that goes from the top front of the motor to a couple connection areas.
