The throttle position sensor is used to control the amount of gas that goes into the engine and thereby determine engine load and control vehicle speed. If it fails, it can result in automatic transmission hard-shifting issues.
Does cleaning throttle body make a difference?
While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability. In fact, if you've noticed a rough idle, stumbling initial acceleration or even stalling – all when the engine is fully warmed up – a dirty throttle body could be the culprit.

Does fuel treatment clean throttle body?
No fuel goes through the throttle body, so adding anything to the fuel tank will have no effect on the cleanliness of the throttle body.
Why does throttle body need coolant?
The reason they have coolant running through the throttle body is to prevent frosting in cold weather. If you live in a warm weather area, you can bypass this in most cases. One of the problems with running coolant through the throttle body is it actually makes the throttle body hot once the engine has warmed up.
Does throttle body affect fuel consumption?
Over time, your engine's throttle body collects debris that can make your engine idle rough and decrease fuel economy.
What are the symptoms of a throttle position sensor?

Can a bad throttle position sensor cause a high idle?
Bad throttle position sensors can cause high idle without causing the Check Engine Light to illuminate.
Can a throttle position sensor 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.
What are the symptoms of a bad accelerator pedal sensor?

Does cleaning a throttle body make a difference?
Cleaning a throttle body makes a massive difference in engine performance and drivability. It will increase the engine power bypassing the required air through the holes. On the other hand, you can also avoid misfires.
How long can you drive with a bad throttle body?
You can drive approximately half an hour with a bad throttle body or more. But it’s harmful to the engine’s health. Your engine will stall and produce excessive heat and other issues by this time. They all together will reduce the engine performance.
Can throttle body cause a misfire?
The throttle body can cause a misfire when it goes bad . If the throttle body cannot offer the right performance, the engine will either get an overflow of air, or it will not get any air. Therefore, it will face problems from starting and running. As a result, the engine will misfire now and then.
Why is my car's fuel consumption so high?
The most common reason is high fuel consumption due to the lower power of your car.
What happens if a catalytic converter goes bad?
If your catalytic converter went really bad, there is a risk that the catalytic converter is not doing its job properly anymore, and this will cause an increment of the car engine’s emissions. The overall purpose of the catalytic converter is to remove emissions, so this is maybe pretty obvious.
Why does my car smell like rotten eggs?
When catalytic converters clog, they restrict the airflow of exhaust gases so that the engine of your car runs on a rich air-fuel mixture. The combustion of this excessive mixture causes an odor like rotten eggs. This smell smells like burnt sulfur, which is an obvious indication of your catalytic converter’s malfunction.
How to tell if a catalytic converter is bad?
The most common symptom of a bad catalytic converter is a sulfur smell when the engine is warm together with a check engine light on your dashboard. You may also notice engine performance issues like acceleration lag, higher or lower fuel consumption, and a misfiring engine.
Why does a hot converter discolor?
The converter discolors’ outer surface due to overheating causes a rich mixture of unburned fuel to enter the converter. This mixture then burns in the converter and melts its inner material, causing blockages. This clogging restricts gas flow through the converter and creates a back pressure that affects engine performance. Thermal damage can also occur when hot converters contact the cold area, damaging their parts.
