Engine Performance problem
1999 Buick Century 6 cyl Automatic 60,000 miles

My car cranks up and idles fine. When i put it in drive and start to accelerate, it begins to sputter as if it can't get gas. It will drive fine one day and then malfunction again the next. i have changed the air filter and fuel filer and the problem still persists. any help would be greatly appreciated.
