Having the right air and fuel mixture in a car’s engine is the only way for it to run at peak performance. Older vehicles really had no way to control the flow of air that came into their engine. With modern vehicles, there are a variety of things that can control the air flow in an engine and among the most effective is the intake manifold runner control. This control mechanism is designed to shut of the air flow when the car is going slower and then increase it as you pick up speed. Every time that your car is ran, this control mechanism will be working to ensure the right air flow is achieved.
Like many other controls and switches on a vehicle, the intake manifold runner control is supposed to last as long as the car does. As time goes by, the hot and humid conditions that this control is exposed to can begin to cause issues. For the most part, this control is not inspected during a routine maintenance procedure, which means that you will only become aware of what it does when it starts to malfunction. Without the right flow of air going through the intake of your vehicle, it will be hard to have a smooth driving experience.
The way that a car idles has a lot to do with the amount of air that it has going through the intake manifold. If the intake manifold runner control is not operating as it should, the vehicle will run a lot rougher than normal. The only way to remedy these issues is by having a professional troubleshoot and replace the bad components causing the disruption.
When the this control is not functioning properly, here are some of the things that you may start to notice:
- The engine is not performing as it should
- The fuel efficiency is decreasing rapidly
- The engine sputters
By having a professional replace the damaged intake manifold runner control, you will be able to have your car back to normal in no time. Due to the sensitive nature of the intake system on a car, attempting DIY repairs will usually cause more harm than good.
