The car will not stay running when i let off the gas pedal.

(1999 Buick Park Avenue)
It started tonight. It was difficult to turn over and when it started I had to floor it to get it to turn over. As soon as I let off the gas it dies. I have also had issue with the fuel gauge for the last year. When the gas tank is low the needle pops back up to full. And then will go back and forth between empty and full

Hi, Have you replaced the fuel filter yet? When was the last time it was changed? As far as the gas gauge goes, the sending unit wiper contacts are worn out and need to be replaced. The unit is accessible from the trunk. You have to take out all the cover mats and it's to the back right of the trunk behind the spare tire well. There is a retaining ring that needs to be removed and the whole unit comes straight up and out. Be sure to clean off any contaminants, dirt or debris around the retaining ring before you remove it. Replacement sending units are available on eBay, at PartsGeek, RockAutoParts, etc. Good luck.
