Throttle body repair; Throttle body cleaning; Idle air control cleaning; DIY method
Here in this video I am illustrating the way to clean Toyota Corolla throttle body. The instructions may work on most vehicles make and models. The throttle body service sure increase the performance of any vehicles whose throttle body is grimed or dirty. This is a routine maintenance on any vehicles to be performed after certain operation. So don't hesitate to perform such maintenance on your car or otherwise stay with poor performance.
Modern electronic fuel injection systems are somewhat the most trouble free systems in any vehicle. However, if the vehicle has accumulated more than 60,000 miles, there is some routine fuel injection-system maintenance that should must be considered. The two most common type car maintenance jobs are fuel injector cleaning and throttle body cleaning. Cleaning fuel injectors is generally not a do it yourself job, but a better DIY person can even do at home. the other consideration is cleaning the throttle body on a vehicle with common tools and un specialized spray cleaners or petrol. While throttle-body cleaning is good preventative car maintenance, it also helps engine drivability. In fact, if you've noticed a rough idle, stumbling initial acceleration or even stalling all when the engine is fully warmed up a dirty throttle body could be the culprit. Once you look inside a throttle body, you will probably be surprised at the dirt, gum and varnish that have accumulated there over the passage of time. Park your vehicle outside in a well lighted, level area. Because throttle-body cleaners are volatile, I do not recommend doing this job indoors. Locate the throttle body under the hood in the engine compartment. The throttle body is located between the air cleaner and the intake manifold of the engine. Most throttle bodies are made of aluminum. The throttle body is connected to the gas pedal of your vehicle with a linkage or flexible cable, which moves the throttle shaft when the gas pedal is depressed. If you're having difficulty locating the throttle body, ask a helper to press the accelerator, with the engine off, so you can see the movement of the throttle shaft. Although there are new cars which are drive by wire systems in which there is no mechanical cable instead there is an electrical harness supplying power to a motor connected with the throttle body. Once you have located your vehicle's throttle body, look at how it is attached to the air-intake tubes. Sometimes throttle bodies are attached with special fasteners called Torx-head screws. If so, you will need Torx bits or Torx screwdrivers to remove these fasteners. More commonly, a flat-blade or Phillips-head screwdriver should do the trick. There may be one or more electrical wires that connect to the throttle body. Do not disturb these; for purposes of this project, you should not need to disconnect any of these terminals. While we always recommend that you follow all appropriate safety precautions for these DIY projects, be extra cautious with this project. Do not smoke when you are working on your vehicle, wear all recommended skin and eye protection and be aware that you are dealing with a flammable spray cleaner. Screwdrivers, Torx bits or Torx screwdrivers or combination or socket wrenches, depending on the fasteners used to connect the throttle body to the intake "plumbing." Toothbrush or small, soft parts-cleaning brush. Note: Some auto parts stores sell specific throttle-body cleaning brushes. Some throttle bodies have special coatings that can be marred by hard-bristle brushes. Eye protection. Flashlight. Materials Throttle-body cleaner. This should be available at

Household oil Cotton swabs Paper towels Rubber gloves The job Park your car outside with plenty of space to work around each side of the engine compartment. As a safety precaution, disconnect the ground terminal (negative) of your vehicle's battery. Locate and label any small hoses that attach to the throttle body or to the air ducts that you must remove to gain access to the throttle body. You can either use masking tape and mark each hose and coupling, or buy specific labeling tape that helps you remember which hose goes with which nozzle/coupling. Remove the air duct that attaches to the throttle body. Be very careful to avoid disconnecting any electrical wires or terminals. The air duct to the throttle body is usually held in place with some type of hose clamp, which can be loosened with a screwdriver, Torx-head wrench, Allen wrench or other hand tool. Sometimes the air duct is pressed into place and can be removed with some gentle twist and pull movements. In some cases, both sides of the throttle body are connected to air ducts by means of hose clamps; in this case, you only need to remove one side to expose the throttle body for cleaning.
