When you're sitting in your car the last thing you want is to have to pay attention to the amount of air flowing through your engine (at least I hope that's not what you want to be doing). That's why you have an Idle Air Control Valve, commonly referred to as an IAC; a little device often found in sports cars used to regulate the flow of air through the car's engine independently of throttle input. This small valve compensates for everything your car's engine needs to overcome in order to maintain its idle speed, and since it's turned off and on by the car's internal computer, you normally don't have to worry much about it. Don't take these valves for granted though: they are often the reason behind car stalls or break downs, so it's important to make sure your car has a good IAC Valve if you want to stay on the road.
Checking Your IAC Valve
If you have noticed your car stalling or poor idle quality in your car, it's most likely time to replace or repair your IAC. Although most problems can be solved by cleaning your IAC (IAC valves are prone to carbon build up which can cause stalling), after a while they'll need to be replaced. To check the valve, remove it from your car motor, andresidue electrical parts cleaner and are still experiencing problems, it's a good sign that the valve needs to be replaced. Although these valves are small, they play a key role in keeping your engine running smoothly and safely.
Buying a Replacement IAC Valve
If it's time to replace your car's IAC, you want to get one that is going to last. Many brands make IAC valves specific to different car brands and models so check to see if there is one made for your car before you buy a standard valve. If you're looking for one of the generic valves, look for products that say they resist abrasion and erosion, for these are common reasons behind IAC valve failure.
Popular Brands include Power Pro, Motercraft, Standard Motor Products, and ACDelco. Each of these brands sell valves that are durable and are made to last, keeping you (and your car) running smoothly.
