Do you ever feel like your car hesitates when you step on the gas? It’s possible that your idle is rough or that your engine revs stay high after stopping. These could be signs that the throttle body is dirty. This is an important part that needs some TLC.
But what is a throttle body, and why is it important to clean it? Let’s jump right in!
What is a Throttle Body and Why Clean It?
The throttle body is like the air entry valve for your engine. It opens and closes a butterfly valve to control how much air goes into the engine. This valve can get dirty over time from engine deposits and oil vapours, which can make it stick or move slowly. This buildup can be removed by cleaning the throttle body, which also restores smooth airflow and may improve engine speed.
Benefits of Cleaning a Throttle Body:
- Better Engine Performance: A clean throttle body lets you precisely control the flow of air, which makes the throttle respond better and acceleration smoother.
- Less Problems With Idling: Dirt buildup can make idling go haywire, but cleaning the throttle body can fix this.
- Possible Improvements to Fuel Economy: A clean and efficient throttle body can help you get better gas economy.
How Often Should You Clean Your Throttle Body?
There is no one right answer for how often to clean. It relies on a number of things, like
- Conditions of the Road: Driving in dusty areas or stopping and starting a lot can speed up the buildup of grime.
- Change the oil: Changing the oil regularly keeps oil vapours from entering the intake system, which lowers the rate at which the throttle body gets dirty.
- What Kind of Car It Is: Some cars just get throttle body buildup more often than others.
As a general rule, check your car’s owner’s instructions to see how often it should be cleaned. If you have any of the above signs, it might be time for a cleaning, no matter how many miles you’ve driven.
Cleaning Your Throttle Body: A Step-by-Step Guide
Disclaimer: Before you do any repair on your car, you should always read the manual. If you’re not sure how to work on your car, you should get help from a skilled mechanic.
As a general rule, here it is. Depending on the type of car you have, the steps may be different.
- Get your tools together: A socket wrench set, screwdrivers, a rag, throttle body cleaner, and (if you want one), a new seal.
- Find the body of the throttle: Most of the time, it’s a butterfly-shaped valve that leads to the air inlet hose.
- Take the battery out: This is a safety measure to keep electricity problems from happening.
- Take the air intake tubes and electrical connectors off: For specific directions, read the manual that came with your car.
- Clean the body of the throttle: Follow the directions on the cleaner to spray it on the throttle plate and inside the case. Use a clean rag to wipe away the dirt. Do not touch the butterfly valve directly.
- If you have one, clean the idle air control valve (IACV): Check your instructions to find out where to put it and how to clean it.
- If you want to, replace the gasket: If the old seal looks worn, you should get a new one.
- Put everything back together in the opposite order: Make sure that all of your links are safe.
- If you need to, reset the idle: Some cars may need to be reprogrammed to stop after being cleaned. For exact steps, look at your manual.
