How is a fuel injector cleaned in a car?
It’s a process of cleaning the electronic throttle body, air intake valves and the fuel injectors which you can find in electronically fuel injected vehicles and the newer vehicles. The throttle body and the plate are manually cleaned by the mechanic or technician using a particular throttle cleaning substance.
How did fuel injection change the throttle body?
Fuel injection systems have since then grown into finely tuned, electronically controlled and operated machines that have improved engine fuel burning efficiency by as much as 70% over the past three decades. The throttle body hasn’t changed much in mechanical design or in function since the early mechanical fuel injection systems were in use.
What is used to clean the throttle body?
Sometimes the throttle body is just cleaned by the injector cleaner entering the engine. But if a throttle body cleaning is performed, the mechanic or technician would first remove the throttle body from the engine. A particular compound called the throttle cleaner is used to clean the carbon. This is a liquid substance and comes in spray cans.
Where is the throttle cable on a fuel injected engine?
On older vehicles, the throttle body of a fuel injected engine is operated by a throttle cable that is either attached to the gas pedal or to an electronic throttle control. The reason you need to consider this fact first is because electronic throttle bodies are calibrated with incredibly tight clearance on the throttle blades.
Why do you need to clean throttle body injectors?
Over time, varnish and sediment clog the screens and injectors, causing inefficient fuel atomization. Many times cleaning the injectors will restore proper atomization and engine performance.
How do you remove a fuel injector from an engine?
Remove the fuel injectors from the engine. Remove the o-ring from the in-flow (fuel rail) side of the injector. Connect the tubing to the in-flow side of the fuel injector.
Why does the idle go up after cleaning the throttle body?
The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel.
Where is the fuel line on the throttle body?
Locate the fuel lines attached to the back of the throttle body. The smaller of the two lines is the fuel inlet line. Find the fuel service port: it will be located a few inches away from the throttle body on the inlet line. Screw the gauge assembly from the cleaning kit onto the service port.
