【TECH TIPS】The Key to Fuel Efficiency and Economy – Throttle Body

With the fuel price hitting record highs, the cost of driving has soared, and the ultimate cost-saving solution is to have a look at your air intake system, as it’s the key to fuel efficiency. In short, the higher fuel efficiency the more cost is saved.

To date, a majority of passenger cars still carry gasoline engines which function through spark-ignition and combustion processes, these operations require accurate control of the airflow, and the throttle body acts as a key role in such accuracy.

How Throttle Body Works

The throttle body locates between the air filter and the intake manifold, by controlling the throttle plate’s movement, it regulates the air-fuel mixture. Each time when pushing down the gas pedal to accelerate, it opens the throttle plate to allow air into the engine, while released, the throttle plate closes and chokes off the airflow. This operation effectively controls the speed of the engine and in turn, the car’s speed increases as well.

Common Issues

Like every part, throttle bodies eventually wear out with time and usage, the common issue is known as coking – with filth and carbon clogged in the throttle housing which leads to malfunction of the throttle plate. Most importantly, a choked throttle body will greatly impact the fuel economy.

The common symptoms of a malfunctioning throttle body include:

Uneven or Failed Accelerating

A malfunctioning throttle body might fail to determine the airflow amount and regulate the fuel-air mixture which then results in a lack of power and cause uneven or failed acceleration. Over time, the issue will affect the longevity of the engine.

Poor Idling & Stalling

The accumulated filth in the system causes the airflow to be turbulent and leads to poor or low idle speed. When deteriorates, it might also cause stalling with rapid acceleration or stopping the engine.

Faulty Corrections

Last but not least, the throttle body is a highly precise part with sensors and wiring to determine the operation and if there is any issue with the throttle body’s performance, it might also alert the electronic throttle control to illuminate the warning light or result in faulty corrections.

When you encounter any of the issues mentioned above, cleaning the throttle body will be the most common and fastest solution. However, it is always better to get it checked by an expert from time to time, when it’s time to upgrade, PartsLINQ offers you the High-Quality option for replacement. Free shipping by DHL.
