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.
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 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.
Honda
The Honda Motor Company is a Japanese public multinational conglomerate corporation—to give them their full title. Primarily a motorcycle manufacturer (since 1959) and engine producer (producing more than 14million each year), Honda became the 8th largest automobile manufacturer in the world in 2015.
How popular is Honda in the United Kingdom?
With around 800k Honda cars on the roads in the UK, this marque is a popular and trusted household name.
Long lasting sensibly-priced cars
On the surface, Honda cars look fairly traditional, but this is a brand that doesn’t necessarily follow the pack; they often provide something unique to each of their models.
For example, the Jazz pitched against the most popular car in the UK, the Ford Fiesta, is actually a more practical option than most of its rivals. For a small car, it has an abundance of interior space and very flexible and practical boot.
The Civic is brave enough to make a strong style in design statement in a market where other brands are edging towards conservative. And the CR-V was the first of the SUV models to stop pretending it was an off-road vehicle and focused its priorities on its road based driving dynamics despite its off-road styling.
Honda motorsports: A long-standing history in Formula One
Honda’s first appearance in Formula One racing as a constructor came in 1964 at the German Grand Prix.
After a mixed introduction, marred by tragedy with the death of driver Jo Schlesser in the French Grand Prix of 1968 Honda took a back seat until their return in 1983 to power the Williams team, where they won 6 consecutive Constructors Championships.
Following the successes with Williams, they partnered with McLaren in 1988, going on to win titles in 4 different seasons.
Their return in 2013, again providing engines for the McLaren team, was met with much less success. After 3 seasons without a single podium finish, Honda was dropped in favour of a Renault built engine.
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.
Common questions about booking at Fixter
Common questions about booking at Fixter
All of our drivers are fully insured and your vehicle is always protected.
We put our drivers through rigorous vetting and training before they are able to drive your vehicle. All of our drivers must have at least 3 years of driving experience, hold a clean driver's licence, be over the age of 21, capable of driving both manual and automatic vehicles and pass a criminal background check.
Your vehicle will be assigned to a driver who is responsible for collecting it from your home, delivering it to the garage and returning your vehicle once all work is completed.
Sometimes we might coordinate with a garage for them to send their own driver to collect your vehicle. In this instance, you are protected as you would be if it was a Fixter driver.
One of our in-house mechanics will factor in the make and model of your car, as well as the work that needs doing. They will then allocate your booking to the most appropriate Fixter garage in your area, and we’ll email you to confirm.
Here’s why only 1 in 20 garages pass our selection criteria:
We only choose garages registered as a Limited Company, with a minimum of 3 years of trading.
We assess each garage's various established affiliations (e.g. Bosch / Unipart / Garage).
We perform an online audit: Fixter only selects garages with at least a 4 star customer rating.
We make sure to visit each garage in person. Our in-house mechanics evaluate the quality of equipment, staff qualifications, capacity, and technical capabilities of selected servicing centres. Fixter only works with garages which strictly use manufacturer-equivalent parts.
After all requirements are fulfilled, we negotiate preferential terms with each selected (including parts, labour, oil, and MOT test rates), so we can pass it along to our customers.
All parts used in repairs and services carried out by Fixter are either manufacturer parts or equivalent. This guarantees that only the best quality parts are used in your vehicle. We offer a 12-month warranty, meaning that should anything should go wrong with the parts or labour we’ll take care of it, free of charge.
We take your card details when you book online, but nothing is charged to your card until all the work has been approved by our in-house experts, and satisfactorily completed.
No extra work will be carried out without your consent. If additional work is required, one of our in-house experts will call you to walk through any diagnostic reports, recommendations or additional quotes from the mechanic working on your car. We check every quote to make sure the work is required and has been fairly priced.
Note: If you need to update your payment details to pay for your booking, the team will send you a secure link to add the new card details.
If your car fails its MOT at one of our garages, but you believe that your car should have passed, you'll have the option to take your car to another garage to do a new MOT test. If your vehicle passes the MOT at another garage, we’ll refund you for the original MOT test that you carried out with us. Collection and delivery fees are non-refundable.
All Fixter bookings are covered by a 12-month warranty on parts and labour.
If there’s a problem (with either parts or labour) up to 12 months after your booking date, we’ll sort it out for you, completely free of charge.
Just email support@fixter.co.uk or call our team on 0330 808 9527 and we’ll take care of it.
Note: this doesn't apply to an air con regas as leaks can occur at any time.
