If your car runs rough when idling, the cause just might be a dirty throttle body. The throttle body controls the amount of air the engine takes in, and when it gets dirty, the engine can't idle smoothly.

Can a dirty throttle body cause reduced engine power?

When the throttle body fails or becomes dirty, it can trigger Reduced Engine Power mode. One of the most common triggers is a problem with the electronic throttle actuator control (TAC) system.

How much does it cost to fix throttle body?

The throttle body part will typically cost between $200 and $500, depending on the type of car that you drive. Labor costs for this kind of repair are typically relatively low, so you can expect to pay between $50 and $150 to have the part professionally installed.

Why is my car saying engine power is reduced?

The reduced engine power warning light shows that something has reduced the flow of fuel and/or air to the engine. It often turns on when a car needs maintenance or repair and doesn't mean your vehicle is about to break down, but it could be a good time for an oil change.

Can a dirty throttle body cause a check engine light?

If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed. This will inevitably contribute to poor engine performance and, if it gets to that point, it should cause your check engine light to come on.

Do fuel additives clean throttle body?

Will a dirty throttle body affect gas mileage?

Over time, your engine's throttle body collects debris that can make your engine idle rough and decrease fuel economy.

Can spark plugs cause reduced engine power?

This causes many problems, like increased exhaust emissions, reduced fuel economy, and reduced engine power. A single misfiring spark plug can cause enough raw fuel to be dumped into the exhaust, causing it to overheat and damage the catalytic converter.

Can you still drive with reduced engine power?

Can you drive safely with the Reduced Power Light on? It depends on the cause of the reduced power. Often, the problems are minor. In rare cases, though, reduced power can cause more serious problems like a seized engine, or even an electrical fire.

What is a throttle body?
