Problems after Cleaning Throttle Body (CAUSES and FIXES)

The throttle body is an important component of the engine, and it needs to be cleaned periodically to prevent a buildup of dirt and debris. A dirty throttle body can cause the engine to run poorly and can lead to decreased fuel economy.

However, with all these problems, you may encounter some issues even after cleaning the throttle body. But what are some of the problems after cleaning?

The main problem you will likely encounter is rough idle, which is often overcome after a couple of starts. However, if the problem doesn’t go away, you have probably done something wrong.

Rough Idle

After you clean the throttle body, it is not uncommon to experience some problems. The most common problem is a rough idle.

You need to re-learn the idle. This can be done by either taking your car to a professional mechanic, or by doing it yourself. If you choose to do it yourself, there are a few things you need to know.

First, ensure your throttle body is at the correct idle position. You can find this information in your car’s service manual. Next, turn off all electronics that could affect the idle, such as the radio and air conditioning. Then, start the engine and let it warm up for a few minutes.

Once the engine is warmed up, slowly increase the RPMs until they reach about 1,500. At this point, slowly release the gas pedal until the engine returns to idle. Now, turn off the engine and restart it. The idle should now be smooth.

If you still have problems after following these steps, take your car to a professional mechanic for further help.

Check Engine Light

One possible reason for your engine light to stay on after cleaning the throttle body is that there is a problem with the throttle position sensor (TPS).

This sensor tells the computer how far open or closed the throttle plate is, and if it’s not working correctly, the car will run rough, and the engine light will stay on. Another possibility is that there is something wrong with the idle air control valve (IAC).

This valve controls how much air enters the engine when it’s idling, and if it’s not working properly, the engine will idle roughly, and the light will stay on. If the car is idling really low, it could be a sign of a vacuum leak.

Car Jerking, Stalling, and Check Engine Light On

If you’ve recently cleaned your throttle body and now your car is jerking, stalling, or the check engine light is on, there are a few possible causes.

One possibility is that you didn’t properly clean the throttle body. If there’s still dirt and grime buildup on the throttle body, it can cause these symptoms. Ensure you follow the manufacturer’s directions carefully when cleaning the throttle body, and clean all the nooks and crannies.

Another possibility is that you damaged the throttle body while cleaning it. If you accidentally scratched or damaged the throttle body in any way, it can cause these symptoms. Be careful when cleaning the throttle body and avoid using any abrasive materials or scrubbing too hard.

If you’ve checked both of these things and you’re still experiencing problems, there may be an issue with the throttle body itself. In this case, it’s best to take your car to a mechanic or dealership to have it diagnosed and repaired.

High Idle

If you experience a high idle after cleaning your throttle body, there are a few potential causes. First, ensure all vacuum hoses are properly connected and not leaking. If the hoses are good, then check the throttle body itself for any debris or buildup that may be causing the issue. Finally, if the throttle body is clean and the hoses are good, it’s possible that the idle control valve is stuck open.

This valve controls how much air flows into the engine at idle, so if it’s stuck open, it can cause a high idle. If you suspect the idle control valve is the problem, have it checked by a mechanic.

how to clean the throttle body

 

A dirty throttle body can cause all sorts of problems, from decreased fuel economy to poor engine performance. Fortunately, cleaning a throttle body is a pretty easy job that you can do at home with just a few simple tools.

Here’s How To Clean Throttle Body:

  1. Disconnect the battery. This will prevent electrical shocks while you’re working on the throttle body.
  2. Remove the air intake duct or hose that connects to the throttle body.
  3. Use a screwdriver or similar tool to remove the screws or bolts that hold the throttle body in place. In some cases, there may be more than one screw or bolt.
  4. Use a clean rag or brush to remove any dirt, debris, or buildup from the throttle body. Be sure to get into all the nooks and crannies.
  5. Use throttle body cleaner and a clean rag to wipe down the inside of the throttle body. Again, be sure to get into all the nooks and crannies.
  6. Reassemble everything in reverse order. Make sure all screws and bolts are tight before reconnecting the battery.

 

And that’s it. Cleaning your throttle body is a pretty simple job that can make a big difference in your car’s performance.

How Does Throttle Body Work?

A throttle body is a component of an internal combustion engine that controls the amount of air that flows into the engine.

The throttle body is located between the air filter & the intake manifold. It regulates the airflow into the engine based on input from the accelerator pedal.

The throttle body is controlled by a cable that is connected to the gas pedal, and when it’s pressed, the throttle opens to allowing more air to flow into the engine.

The amount of air that flows into the engine determines the amount of power that the engine produces. If too much air flows into the engine, it can cause the engine to stall or run rough. If not enough air flows into the engine, it can cause the engine to run lean and produce less power.
