The engine requires fuel to turn the wheels and get you to your destination. The way fuel moves from the tank to the carburetor or injectors involves a large number of moving parts, so there are many things waiting to go wrong. One of those is the throttle, which is the connection with the amount of power sent to the wheels. The last thing you need while driving is to find that your engine won’t do what you want, so your throttle needs to be looked after.

It goes without saying that your throttle is one of the most important parts of your vehicle, and it needs to be operating at 100% if you want to get the best from your engine. When it is working at its optimum level, it will allow your engine to run smoothly and maintain fuel efficiency by using the right amount of air and fuel. At its best, it can give you the amount of power you expect without wasting fuel, but at its worst? Well, things can go wrong very quickly.

Your throttle is made up of a number of different parts, and most of them can be found between your accelerator pedal and the injectors or carburetor on the engine. On older engines, you will find a throttle cable running to the throttle body, but newer engines use computer sensors to give you more precise control over your accelerator. The throttle body, used on all types of engines, is perhaps the central part of your throttle, and this can normally be found towards the back of the engine in a central location.

Because there are so many parts involved in the process of accelerating, there are also a number of things that can go wrong. For instance, the throttle body can become clogged with contaminants from the fuel and the valves, inside the body, can stop working as they are supposed. The fuel and air lines running to and from the body can become clogged or even rupture, and throttle cables on older engines will eventually fray and fail over time. On more modern engines, you even need to be concerned with the sensors that feed information to the computer, so there are a lot of things to consider!

Considering all the things that can fail with your throttle, the symptoms are surprisingly obvious and sudden. Your engine can begin to become starved of fuel or oxygen, which will be noticeable because you will feel a loss of power when you accelerate. You can also notice a hesitation when you accelerate, because the throttle does not immediately send the right mix of air and fuel to the injectors or carburetor. In more rare, and extreme, cases, you may also find that the vehicle is difficult to start because it is not getting the extra fuel it requires.

    The throttle controller will basically bypass the computer in the vehicle. It is designed to take the information right from the accelerator position sensor and compile it in a high speed controller circuit that compiles the signal sent from the Accelerator position sensors. With this controller you are able to program it to different options and the throttle response timing will be noticeably faster.
