There are two valves in the back of the intak called 'Intake Runner Control Valves'. Do a search for these. I don't know a lot about them, but I do know that they can get stuck in one position or the other. Or hopefully you just have a broken wire somewhere in the circuit. I'm sure Quitin or Bluegrass will be along shortly and can tell you more.
