Step 1

Start with disconnecting the air duct from the throttle body. You will have no problems in finding it as it’s similar to a hose and, as a rule, it’s attached to the functional part of throttle body where it intakes air.

Unscrew the air duct from throttle body and denote any openings plus electrical connections which are going through it.

Step 2

After that, spray the throttle body cleaner in the opening, taking into account that it’s protected by a butterfly. To open the throttle, detect the throttle cable and pull it.

As soon as the throttle is open, spray heavily the throttle cleaner after placing it in the opening. Check if the spray reaches everywhere.

Step 3

The third step is the most complicated one. Initially, air compressor arrangement is required. When you do that, spray air inside the throttle body holding your hand stable. The compressed air will assist in drying the cleaner liquid plus will prevent it from capturing dust.

Step 4

Finally, take a paper towel or a clean piece of cloth to clear the outer part of the throttle body. Install the air duct back in its place. Double check if you place all the electrical wires plus equipment correctly. Seal the air duct hermetically. If it’s sealed badly, it will prevent the throttle body from normal operation.

Congratulations! The cleaning process is over. If you have followed all the instructions properly, be sure that now your throttle body is absolutely clean and will contribute to enhanced functioning of your motor. Now, it’s time to discover what the most trustworthy throttle body cleaners are plus how to choose the most appropriate one for your motor.
