What problems can a faulty throttle body cause in a car?

[MayaAnn]

A faulty throttle body can cause the following problems in a car: unstable engine idle speed, persistently high idle speed, difficulty in engine starting, unstable engine idle speed, and no idle speed. The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake manifold, it mixes with gasoline to form a combustible mixture, which burns to produce power. It is connected to the air filter at the top and the engine block at the bottom, and is referred to as the throat of the car engine. There are two types of throttle bodies: the traditional cable-operated type and the electronic throttle body. In traditional engines, the throttle body operates through a cable or linkage, with one end connected to the accelerator pedal and the other to the throttle linkage plate. The electronic throttle body primarily uses a throttle position sensor to control the throttle opening angle based on the engine's required power, thereby regulating the amount of air intake.
