Can a bad throttle body cause an unstable idle?
Can a bad throttle body cause an unstable idle?
A problem with the idle air control valve, which is usually mounted to the throttle body, can cause an unstable idle as well. A faulty throttle body may disrupt the engine’s air/fuel mixture, resulting in misfiring and a rough running condition. This is pretty rare, however.
When to address a bad throttle body assembly?
The quick answer is no. Once it starts to show signs of going bad or being clogged, you should address the problem right away. Otherwise the vehicle may stall or fail to accelerate, creating a safety hazard. Both types of throttle body assemblies (mechanical and electronic) are located between the engine air filter and intake manifold.
Where are the throttle bodies located in a car?
Both types of throttle body assemblies (mechanical and electronic) are located between the engine air filter and intake manifold. Most cars use just one throttle body, though some engines (usually those with twin turbochargers) use two throttle bodies.
When to keep your fingers out of the throttle body?
KEEP YOUR FINGERS OUT OF THE THROTTLE BODY AT ALL TIMES!!! The car’s primary computer, which is often referred to as the powertrain control module (PCM), expects to see a certain amount of airflow through the throttle body. When that doesn’t happen, because the throttle body is dirty or faulty, the engine may stall.

Why do you need a throttle body in a car?
The throttle body has been a vital component since fuel injection systems became more popular than carburetors beginning in the early 1980’s. Fuel injection systems have since then grown into finely tuned, electronically controlled and operated machines that have improved engine fuel burning efficiency by as much as 70% over the past three decades.
Where is the throttle cable on a fuel injected engine?
On older vehicles, the throttle body of a fuel injected engine is operated by a throttle cable that is either attached to the gas pedal or to an electronic throttle control. The reason you need to consider this fact first is because electronic throttle bodies are calibrated with incredibly tight clearance on the throttle blades.
