GMC Sierra Surging on acceleration

Help. My 1999 GMC Sierra, 5.3 Suges affter accelration and re application of the gas. In short, I can accelerate and then take my foot off the gas, hit the throttle again and it beginns surging. Tach moves 300-500 RPM. Solid application of the gas stops it. Any Ideas?
