Dodge Repair: 03 Dodge Durango, volt supply, signal circuit

Question
My durango was running fine tilllast week. When I took my foot off the gas it would stall and cut off.I found 2 codes for my problem.P0108 & P0441.I replaced the MAP sensor. And cleaned the IAC. Now I have the codes: P0411 Secondary Air Injection System Incorrect Flow Detected and P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input . When I go to put the hose back on the IAC it will stall the motor. If I leave the vac.hose off the car will run???? I'm confused here andon't know what else to do with it?
