What is the Idle Control Valve all about?

The Idle Control Valve is designed to control and maintain a consistent engine idle speed. The valve helps counter anything the driver may do to put extra load on the engine, such as turn on the air conditioning, sound systems, lights, etc. When the car is cold, the idle control valve helps the engine start.

Keep in mind:

The idle control valve usually goes bad because of excessive carbon buildup in the intake manifold.

How it's done:

Scan the computer system in the car for codes.
Check for any vacuum leaks.
Check electrical connections.
Remove and replace the idle air control valve if faulty.
Clean carbon out of intake manifold ports.
Clear Engine Check light.

Our recommendation:

It is a good idea to get an air induction service performed every 3 to 4 years. This will ensure that the carbon does not build up on the valve. When you are getting the idle control valve replaced, your mechanic should inspect the vacuum lines for leaks. If the vacuum is leaking, it will mimic the symptoms of a bad IAC valve.

What common symptoms indicate you may need to replace the Idle Control Valve?

When the engine is idle, (car not moving), the engine may stall.
Excessive racing noise from the engine.
Engine may shut off if AC is turned on.
Check Engine light is on.

How important is this service?

The idle control valve is responsible for maintaining a constant and consistent engine. It achieves this by ensuring that the idle speed is always constant. Many factors – such as a cold engine, the radio, or the air conditioning – effect the idling speed of the engine, so the idle control valve neutralizes these outside factors, and makes sure that the engine is consistently idling at a stable speed. When the idle control valve malfunctions, the idling speed is no longer regulated. This means that if you turn on the radio or the air conditioning, which requires power, your engine may stall. It also means that your vehicle may not be able to turn on.

Porsche 944 L4-2.5L Turbo - Window Motor / Regulator Assembly Replacement (Driver Side Front) - Dallas, Texas

Kyle is fast, knowledgeable, and professional. I had the driver side power window motor go bad. He originally came out and inspected it, and verified that the motor was the problem, and noted that the regulator (the armature that does the actual lifting) was old and a bit weathered, suggesting I replace both at once. I sourced the parts myself, and scheduled Kyle to come back out to do the replacement. He contacted me ahead of time and offered to come earlier, as it was in both of our interests. He arrived on time, called upon arrival, made the repairs, and reassembled everything properly. I would highly recommend Kyle and plan to request his services when I have the timing belt and water pump replaced. (a normal Porsche 944 maintenance item every 30,000 miles.) Thanks again Kyle!
