How to clean TBI fuel injectors

Fuel injectors and intake valves are the most important components of a car engine. They play a significant role in enhancing the performance and fuel efficiency of the car.

A lot of people think that the only thing they need to do is to change their air filter every few months or so.

However, this does not clean out all of the dirt that might be getting into your fuel injectors, which is why they should also be cleaned from time to time.

In this article, we will provide you with some information about how to clean TBI Fuel Injectors and what are the benefits you will receive from doing so.

Step by Step: How to Clean TBI Fuel Injectors

There are many ways to clean TBI fuel injectors, but it is important to know that they all use different steps. Knowing how to properly clean TBI fuel injectors can improve your car’s performance and make it last longer.

The first step for cleaning TBI fuel injectors is to find out if you need a gas additive or not. If your car’s engine has more than 200,000 miles on it, then the answer will be yes.

The second step is to use a bottle of high-quality gas treatment like OnTBI (a proven gas additive). 

Next, you should fill up with fresh gas and drive around for 20 minutes or so before restarting the engine. You should also take the time to replace the filter in your vehicle’s air filter system.

Here is a detailed process of Clean TBI Fuel Injectors:

1. Replacing fuel filter 

Replace your fuel filter and run a fuel system cleaner, like the Lucas Fuel Treatment + Water Remover through your fuel tank.

This remedial additive enhances performance while enhancing drivability for smooth starts and spectacularly clean emissions. 

Additionally, it helps eliminate water in your fuel while keeping the injector from rust. It also helps to remove any build-up in old gas lines that might be causing problems down the road.

2. Remove air cleaner

Remove or flip up the air cleaner to access the throttle body underneath. Unlock the clamp atop the intake tube and hold it in place while you loosen the mounting screws.

Lower the air filter away from its housing and wait for more fumes to clear from inside before proceeding.

3. Disconnecting the battery

Disconnect the battery terminals to prevent fire or shock. Also, wipe down any remaining dust and debris from the mounting bracket and back of the air cleaner of all connections and top surfaces. 

You don’t want dust dropping onto your polished housing or into your mass airflow sensor while you work.

Working outdoors in a well-ventilated area can help protect you against exposure to noxious vapors that might otherwise pose an inhalation hazard.

4. Cleaning throttle body area

Slowly remove the butterfly of the engine, and spray the entire area thoroughly with throttle body cleaner. This kind of spray cleaner is available at auto parts stores. 

Do not use carburetor cleaner as this will damage the plastic of the throttle body. Using a toothbrush or small parts brush, clean all of the dust and debris from under the cover that surrounds the teeth on which the butterfly sits.

5. Cleaning injectors with throttle body cleaner

Spray the injectors with a throttle body degreaser, and clean them with a bristle brush. You should never insert any kind of metal objects inside the injectors because this could permanently damage them.

6. Reassembling 

Replace the air filter assembly when you are done, and start your vehicle up again.

The car may struggle to start or idle at first because the engine is degreasing itself of harmful residue to improve performance. Let it idle for two to three minutes before driving it around for a test run.

Benefits of Cleaning TBI Fuel Injectors

Fuel injectors are used to mix the right amount of fuel and air in an engine. To optimize fuel combustion, they have small channels that allow for injections of liquid or gas directly into the engine. 

These injectors can be subject to contamination from carbon deposits from incomplete combustion, water, coolant, and oil.

As such you need to clean your Fuel injector regularly. Cleaning TBI fuel injectors has many benefits, including:

  • Improved gas mileage
  • Reduced emissions
  • Reduced engine wear and tear over time
  • Prevent corrosion and pitting
  • Efficient performance of the engine 

The solution to a clogged fuel injector is a DIY project. You can clean your fuel injectors with household items such as dish soap and water.

TBI fuel injectors are responsible for making sure that the air and fuel mixture is delivered to the engine in the right ratios. Usually, when TBI fuel injectors get clogged, you would need to replace them. 

However, before you do this, there are some things that you can try. One of these is cleaning them with cleaner spray. 

When cleaning TBI fuel injectors, be sure not to let the cleaner get into the engine’s cylinders or onto any other part of the engine where it could cause damage or injury. 

Another thing to note is not using anything abrasive because this could scratch and damage your TBI fuel injector even further than it was already damaged by neglecting it in the first place.
