If your Lexus moves like a snail, hesitates to accelerate, or drinks fuel as never before, there is a high probability that you have clogged fuel injectors. Fuel injectors are important to pump the fuel to the engines in the desired quantity. Sometimes they become filled with dirt or residues that greatly affect your car’s performance, distort its fuel consumption rate, and may cause harm to the engine in the long run. Fear not— cleaning clogged fuel injectors isn’t something that has to remain a mystery. This guide will help you to easily clean your Lexus fuel injectors and bring back the power and efficiency of your car.

What are Fuel Injectors and Why Do They Get Blocked?

Fuel injectors are small devices that help to deliver fuel from the fuel line into your engine’s combustion chamber in the form of a mist. This precise delivery is what makes your Lexus have the required combustion which provides the power for the running of the engine. But, with time, dust and grime, together with carbon deposits tend to accumulate on the injectors blocking them. This can be accelerated by using dirty fuel, irregular or infrequent servicing, or the use of poor quality gasoline for a long time. The dirt in the injectors hinders the flow of fuel, which results in low performance, rough running and even stumbling.

How to Clean Clogged Lexus Fuel Injectors

Locate the Fuel Injectors

To diagnose a vehicle with a bad injector the first thing that should be done is to take off the hood of the car to reveal the fuel injectors. If you need to, consult your owner’s manual but most Lexus models have injectors connected to the fuel rail that transfers fuel from the tank to the engine. Before you continue make sure the engine is fully cold; otherwise, it’s likely to burn or cause some other accident during the process.

Use a Fuel System Cleaner

If you think that there may be minor blockages, a fuel system cleaner will come in handy. Choose an excellent cleaner that would be ideal for your car make and model. Add the cleaner into the tank of your Lexus as per the product’s directions and drive your vehicle for 50 to 100 miles to allow the cleaner to work around the system and dissolve the deposits. This method is simple, used to prevent clogs, and is best for minor clogs that are easy to clear.

Disconnect the Fuel Injectors

If the clogs are not very easy to dissolve then it may be necessary to clean the fuel injectors directly. First of all, disconnect the battery connection just in case. Then, carefully take out the fuel injectors from the fuel rail being careful not to destroy the seals/connectors. If this step looks like a boring or tiring task, it is wise to consult an expert and avoid damaging the injector or the neighboring components in the process.

Use Fuel Injector Cleaning Kit

In extreme cases where a blockage is seriously affecting the performance of the fuel injector, the use of a cleaning kit can be very useful. Connect the kit to the injectors according to the manufacturer’s instructions, introduce the cleaning solution to the kit, and wash the injectors.

Reinstall the Fuel Injectors

Once cleaning is done, properly replace the fuel injectors. Replace any screws or bolts you unscrewed while undertaking the process and reconnect all the seals, wires, or hoses that you removed in the process.

The fuel injector is a very sensitive part so it’s wise for you to always consult a professional mechanic rather than trying to do it by yourself.
