Rough or hunting idle? Stalling? Sputtering? These are all symptoms of poor fuel delivery or a vacuum leak in your intake system. This T-shaped idle regulating valve is one of the areas that you can check to fix these issues. The ICV is basically a electrically-driven throttle body that regulates the air/fuel mixture at light throttle openings. Over time, the ICV can become gummed up with oil and carbon, resulting in slow or blocked operation. Worst case, the electric motor inside will freeze which will stall the engine.
The ICV will typically need to be cleaned or replaced every 100k miles. It can be cleaned with carb cleaner but for seriously dirty or old ICVs you may want to replace the whole unit with a new one. You may also want to replace the Crankcase Vent Valve as it can also fill up with oil and carbon and replacement can be done at the same time as the ICV. On cars with V8 engines, we recommend replacing the rubber grommet between the valve and the manifold - Part # 13411733217
