Low Engine Idle and/or Stalling Due to Dirty Idle Air Control Valve on Toyota Avalon

Problem Description and Possible Solution

Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.

When I start the car the idle is 2.2 it use to 1.7. It takes longer to idle it down to .09. What causes this to happen?
It is very intermittent on low idle and dies. Haven't solved yet been living with problem for several months.
Car started, but stalled immediately revs dropped very low. Replaced ICV ($400 plus labor) and car is fine.
Idle was erratic, sometimes racing, sometimes it wouldn't idle without pressing throttle. Had mechanic clean the IAC valve and fixed the problem.
My car would stall out when I tried starting it. The engine turns over, but stalls out immediately unless you keep your foot on the gas.
Started with an unusually rough idle. Slowly progressed to near dying idle at around 400 rpm. Engine refuses to accelerate under 2000 rpm. Will buy new valve and replace asap. Without it im getting around 8 miles to a gallon when i normally get 25.
