Common questions

Can I use petrol to clean throttle body?

Can I use petrol to clean throttle body?

The aerosol spray will not clean all areas, particularly the back side of the throttle plate. A tuneup/injector cleaner mixed with gasoline (1:4 or 1:5 ratio) should be safe. You won’t be using much, and you can pour the rest into the gas tank after you’re done.

Can I use WD40 to clean throttle?

WD40 won’t be an effective throttle body cleaner, hard deposits stuck to the throttle body and throttle plate will require a throttle body solvent. Throttle body cleaner is formulated to help breakdown carbon and other fuel related deposits on a throttle body.

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.

Why do you need a throttle body in a car?

The throttle body has been a vital component since fuel injection systems became more popular than carburetors beginning in the early 1980’s. 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.

Why does the engine speed increase when you open the throttle?

Air flowing through a venturi, draws a fixed amount of fuel based on the size of the jet. More air entering through the carburetor, means more fuel and an increase in engine speed. With this system, as we open the throttle the speed increases, because we draw in more fuel.

How does fuel injection control the idle speed?

Early fuel injection normally uses an idle air control or IAC valve to control the speed of the engine’s idle. They use several designs, but most work in a similar manner. On early vehicles, General Motors often uses a stepper motor that turns a thread valve.

How to install a new throttle position sensor?

Install your new sensor by working backward through the removal steps. Start by installing the sensor using the mounting screws. Next, connect your sensor to your vehicle’s electrical system using a convenient electrical connector. You should be able to easily push it together and hear a distinct click. Check to ensure a firm connection.

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.
