How to Remove the Throttle Body From a 98 Honda Civic
As with virtually all modern automobiles, the 1998 Honda Civic uses a throttle body instead of a carburetor. The throttle body determines how much air and fuel enters the engine when the gas pedal is depressed. Similar to carbureted engines, changing the throttle body to one which flows more air and fuel will increase the horsepower produced by the engine. Replacing the stock throttle body with an aftermarket unit requires the removal of the existing throttle body. Fortunately, removing the old unit is simple to do and takes only a few minutes.
