Our expert insights into throttle body replacement
What does a throttle body do?
The throttle body is a critical piece of the air intake system that controls the amount of air flowing into the engine. It consists of a pivoting flat valve and is located between the air intake and engine manifold where fresh air is pulled into the engine for the combustion process.
What are the symptoms of a bad throttle body?
Below are the top three symptoms that could indicate you need to replace your throttle body:
A very poor or rough idle
Poor or unreliable acceleration
Excess fuel consumption
What happens when we do a throttle body repair on your car?
Our certified mechanics will:
Analyse the ECU to see if there are any related fault codes.
Inspect the throttle body and air intake system.
Replace the throttle body if there are issues with it.

What does a throttle body do?
In today's modern fuel injected cars, the throttle body is a critical piece of the air intake system that controls the amount of air flowing into the engine. It sits between the air intake and engine manifold where fresh air is pulled into the engine for the combustion process.
The throttle body itself consists of a tube containing a pivoting flat valve (butterfly). When the driver presses the acceleration pedal the butterfly in the throttle body pivots to let more air flow into the manifold. When this happens, the throttle position sensor reports to the ECU that you have pressed the accelerator. The airflow sensor then detects more air and sends a message to the car’s computer to boost the amount of fuel being supplied by the injectors. This whole process is what enables your car to accelerate.
A good air filter is absolutely critical to the healthy operation of the throttle body, because dirt buildup on its surface over time can cause the butterfly valve to stick, causing a rough idle and drivability issues. It is therefore important that both the air filter and the throttle body are well maintained and kept clean.
Smart
Smart is a German automotive brand, established 25 years ago in 1994.
The company is a division of the automotive corporation Daimler AG and operated under the ownership of Mercedes-Benz.
How popular is Smart in the United Kingdom?
Smart isnt’ the most popular brand in the UK, most likely due to appealing primarily to parking-challenged city-dwellers; there are only 96k of their vehicles on the roads of the UK today.
Showing steady growth, however, since their introduction to the UK market in 2003, the trend would suggest that we’re likely to see more of these eccentric looking tiny cars as time goes by.
Smart: Quirky little microcars and subcompacts
Owned by Mercedes-Benz, Smart cars fit into the market you’d expect on first glance. They’re a fun and funky little city car; they’re solid, middle of the road machines, designed to be as versatile as they look.
A Smart car will never fool anyone that it’s a hi-end, luxury vehicle. There’s plenty of glossy plastic and groovy fabrics, yet in the cockpit, you’ll find up-to-the-minute touchscreen media options at the controls. They do come at an inflated price for the small city car market, but by nature of their unique design—there’s nothing quite like them.
Smart cars are cheap to run—but not so cheap to buy
Your Smart ForFour will be more expensive by comparison than its rivals: the Fiat 500, Skoda Citigo, Kia Picanto or Hyundai i10—yet it’s rather hard to pitch the Fortwo against anything because there isn’t anything on the market quite so small. Only the Renault Twizy comes to mind, and that’s barely a car at all.
Once you’ve got one though, your Smart car will cost next to nothing to run with their tiny wheels and low weight. The electric models perform even better with a fuel equivalent of 87mpg.
How often should a throttle body need replacing?
In today's modern fuel injected cars, the throttle body is a critical piece of the air intake system that controls the amount of air flowing into the engine. Because it is crucial to the healthy running of your vehicle, the throttle body should be well maintained and cleaned at least every 75,000 miles.
If you begin to notice any signs that your throttle body might be failing, such as a rough idle, frequent stalling or unreliable acceleration, you should book your car in to have the air flow system and the throttle body inspected as soon as possible. When the throttle body begins to fail it will get progressively worse (and more dangerous!) over time.
What happens during a throttle body replacement?
Our certified mechanics will:
Analyse the ECU to see if there are any related fault codes.
Inspect the throttle body and air intake system.
Replace the throttle body if there are issues with it.
Clean the air intake system of dirt and residue.
Advise if any other parts need to be replaced.
Finally they will run the engine and test drive the car.
What causes a throttle body to break?
Like most car parts, over time the throttle body will experience wear and may begin to fail. Another common issue is caused by the filth, carbon, and dirt that can build up in the throttle body housing and air intake system, creating problems with air flow. This interrupts the perfect mixture of air and fuel and can cause the butterfly valve to get stuck. Therefore regular cleaning and maintenance of the system and throttle body is crucial for a healthy and reliable car.
What are the symptoms of a bad throttle body?
Usually, there a few signs you can look for:
A very poor or rough idle
Poor or unreliable acceleration
Excess fuel consumption
Car misfiring
A delay from when you step on the acceleration until the car responds
A visibly dirty throttle body
Stalling more frequently
Check engine light comes on
How often should you replace your throttle body?
There is no set lifespan when it comes to the throttle body, however it is suggested that you clean it thoroughly at about 75,000 miles. Cleaning the throttle body and air intake system allows your car to operate more smoothly and it helps prolong its life.

What is the average life of a throttle body?
There is no set lifespan when it comes to the throttle body, however it is suggested that you clean it thoroughly at about 75,000 miles. Cleaning the throttle body and air intake system allows your car to operate more smoothly and it helps prolong its life. Like with many car components, if the throttle body is well serviced and properly maintained it should last a while.
Can you drive with a bad throttle body?
Driving with a bad throttle body is not recommended. Your car could be very difficult to handle, it could break down whilst driving, or it could even accelerate unpredictably and uncontrollably - which is a very dangerous situation to be in on the roads. When the throttle body begins to fail it will get progressively worse (and more dangerous!) over time. You should book your car inn to be looked at as soon as you suspect there may be a problem.
Does the throttle body deteriorate with age?
Like most car parts, over time the throttle body will experience wear and may begin to fail. Filth, carbon, and dirt can also build up in the throttle body housing and air intake system over time, creating problems with air flow. This interrupts the perfect mixture of air and fuel and can cause the butterfly valve to get stuck. Therefore regular cleaning and maintenance of the system and throttle body is crucial for a healthy and reliable car.
The law, vehicle regulations and your MOT
If your throttle body is failing it could be affecting your fuel consumption and emissions. Because there are strict regulations around car emissions in the UK, excess fuel consumption and emissions could result in a fine or an MOT failure. It's important to keep your car well maintained to avoid unnecessary costs and harmful emissions.
