Stalling out when i am driving on 2001 Buick Park Avenue

When i am driving my car it starts to jerk and jerk and when i give it gas it jerks and quits. Then when i crank it up i can go for a while then it does it again.

This can be many things. Have a shop connect to the computer and read out the fault codes, this will help to determine what is causing this problem.

Sounds like a vacuum line- after a period of time the vaccum line connections become weak. It should be worse at idle and much better on acceleration. Usually the "race track" line- Looks like a race track on the left side- If it is that cost about $24 from the dealer. Good Luck
