In the case that the problem is caused by bad idle operation, it’s likely that this problem is cause by a faulty idle air control valve. This air control valve of the engine is responsible for controlling the engine revolutions per minute and, when faulty, the vehicle will accelerate on its own.
What do you do when your car accelerates on its own?
What would cause a car to accelerate?
How Does a Car Accelerate? To develop the power to quickly accelerate, an internal combustion engine needs to breathe. Here's how: It takes in a precise amount of air and fuel that is compressed and ignited in the combustion chamber, then exhaust gases are quickly exhaled out the tailpipe.
Can cars accelerate on their own?
Sudden unintended acceleration is a glitch that happens when the vehicle (supposedly) accelerates on its own without driver input. In some cases, drivers also complain of loss of braking ability during an unintended acceleration event.

What will a bad throttle body cause?
A faulty throttle body may disrupt the engine's air/fuel mixture, resulting in misfiring and a rough running condition.
How much does it cost to replace a throttle body?
The average cost for a Throttle Body Replacement is between $489 and $593 but can vary from car to car.
How much does it cost to replace an electronic throttle body?
To replace your car's throttle body, you will pay as little as $370 or as much as $1,500. Labor should be between $70 and $260, and parts should cost you from $110 to $600.
Can bad throttle body cause transmission problems?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems. When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle.
Does a throttle body need a gasket?
The throttle body gasket is one of the most dispensable parts of a car. The throttle body should be replaced every now and then. When there is a leak, it should be changed.
What are throttle bodies?
The throttle body is an important part of your air intake system that controls the air flowing into your engine. It's located between your air intake and engine manifold where fresh air is pulled into the engine for the combustion process.
Is it worth replacing throttle body?
The throttle body plays a large role in controlling the fuel and air mixture in your engine. The proper mixture needs to be achieved in order for your engine to run smoothly and properly. Once this part fails, it needs replacing rather than repairing.
How often does a throttle body need to be replaced?
At what mileage should this service be done? There is no specific mileage requirements and some cars may never need this service. A throttle body usually gets dirty at higher mileage (after 60K-80K miles), mostly in cars that are often driven in stop-and-go city traffic or when oil changes are not done regularly.
Can a throttle body be fixed?
Once the problem is identified, then a new throttle body will need to be installed on the air intake system to fix the problem. So if your engine light is on, or you know your throttle body needs to be replaced, make sure you've got an experienced shop working on it right away.
Can I clean throttle body without removing it?
You don't need to remove a throttle body to clean it. If you have a DBW throttle body, DO NOT MOVE THE THROTTLE PLATE MANUALLY TO CLEAN IT, especially with the key in the ON position. Have them depress the gas pedal all the way to open the throttle plate so you can gain access to do your cleaning.
What causes an electronic throttle control to go bad?
In this case, the problem may be caused by a miscommunication link from the throttle controller and the engine's air fuel mixture which is regulated by the mass air flow sensor on many cars. In most cases, issues with the throttle controller are electric, either caused by a damaged sensor or electrical relay.
What happens when the electronic throttle control goes bad?
When a TPS goes bad, then the car's throttle body won't function properly. It could either stay shut or it won't close properly which is a severe issue. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.
What does the throttle actuator do?
What is the throttle kicker actuator? A Throttle Kicker Actuator is a component of the throttle control which helps to regulate throttle control in situations where additional throttle is needed suddenly or when there is a sudden drop in throttle needed.
