I wonder if this is what you have for a code:
P2004-INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN

From the service manual:

When Monitored:
With the engine running, when the valve closes, below a calibrated RPM, depending upon pedal position.
Set Condition:
The Powertrain Control Module (PCM) detects that the position feedback of the Manifold Flow Valve Position Sensor is not within range of the adapted value learned during in-plant initialization or after a non volatile memory reset (adaptive memory clear).
Possible Causes:
  • (K857) 5-VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE
  • (K602) MFV SIGNAL CIRCUIT SHORTED TO VOLTAGE
  • (K857) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
  • (K602) MFV SIGNAL CIRCUIT SHORTED TO GROUND
  • (K857) 5-VOLT SUPPLY CIRCUIT SHORTED TO (K900) SENSOR GROUND CIRCUIT
  • (K602) MFV SIGNAL CIRCUIT SHORTED TO (K900) SENSOR GROUND CIRCUIT
  • (K602) MFV SIGNAL CIRCUIT SHORTED TO THE (K857) 5-VOLT SUPPLY CIRCUIT
  • (K857) 5-VOLT SUPPLY CIRCUIT OPEN OR HIGH RESISTANCE
  • (K602) MFV SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE
  • (K900) SENSOR GROUND CIRCUIT OPEN OR HIGH RESISTANCE
  • (Z909) GROUND CIRCUIT OPEN OR HIGH RESISTANCE
  • MANIFOLD FLOW VALVE
  • INTAKE MANIFOLD
  • POWERTRAIN CONTROL MODULE (PCM)

It is usually a warped intake manifold not allowing the runner valve to come back to the proper position. You can try and replace the valve assembly itself but if the code comes back it will need the intake manifold.
