The throttle body’s core function is to regulate and control the amount of air allowed to enter the engine. The throttle body of your vehicle is basically a butterfly valve. Refueling less frequently might sound like a good thing, but your engine doesn’t think the same in the long run! What Is a Throttle Body?

If the engine is not receiving proper air supply due to a damaged throttle body, the engine will suffer, and as a result, the driver would experience a drop in performance. The engine requires both adequate air and fuel supply to perform effectively. Usually, a throttle body cleaning and a throttle body calibration with a diagnostic tool will solve this problem. This is often caused when there comes a lot of soot and dirt on the throttle body flap, which will cause less air entering the engine and therefore cause a low idle RPM. It can cause the RPM to be so low at idle so that the engine will die. The throttle body can affect the RPM the other way also. You can calibrate the throttle body with most diagnostic scanners. If there is a problem with the throttle body, it may cause the be way too high.Ī not calibrated throttle body can also cause this. The throttle body controls the engine’s idle to make sure it is always holding a steady RPM. Misfires are easiest recognized as small bumps when you are revving the engine. It is incomplete combustion inside the combustion chamber, in other words.Īs we told you before, a bad throttle body can mess with the air-fuel mixture, and it can also cause your engine to misfire. Misfires occur either when the air-fuel mixture is very wrong or when it comes to a weak spark from the spark plug. If you notice that your car has a very uneven acceleration – sometimes it is fast and sometimes slow, you might have a bad throttle body. This means that a faulty throttle body can mess the air-fuel mixture up, which will cause problems when accelerating. The throttle body is also regulating the air-fuel mixture that is entering the engine. The car engine is most sensitive at idle, where you will notice symptoms of a dirty or bad throttle body first. If you notice your car’s engine idle is jumping up and down and make strange sounds, it may be due to a dirty or damaged throttle body. The check engine light also comes on due to several other reasons, which is why we recommend to visit an auto specialist and have the car scanned for any trouble codes when it pops up on your dashboard. As soon as the car’s onboard computer detects a problem with the throttle body signal, it will cause the check engine light to illuminate. The throttle body has some angle sensors and other sensors installed inside of it. Throttle Body Replacement Cost Bad Throttle Body Symptoms 1.
