Hello! The throttle body is the part of the air intake system that controls the amount of air that flows into an engine's combustion chamber... It consists of a bored housing that contains a throttle plate (butterfly) that rotates on a shaft... When the accelerator (gas pedal) is pushed down, the throttle plate opens and allows air into the engine.. When the gas pedal is released, the butterfly closes and effectively chokes-off (throttles) air flow into the combustion chamber... This process effectively controls the speed of the engine and ultimately the speed of the vehicle...Guru...saailer

Can i get some steps and tips for cleaning the throttle body on a buick century 3.1 2000

There are spray cleaners for that purpose available at auto parts stores.
Spray it all over the inside if the throttle body without the engine running. Let it sit for a while to loosen the dirt. Spray again and then start the engine. Spray more to clean past the throttle plate.

Why does ford use coolant in the throttle body of 1998 ford ranger 2.5l fuel injection engine ?

they ran coolant lines to the throttle bodies for emission purposes the coolant actually is used to heat the air entering the intake manifold to help preheat your air fuel mixture so less hydrocarbons are made during the combustion cycle however this preheating reduces actual horsepower produced at the flywheel by as much as 10% according to many dyno tests, there really is no proof of any mileage gain or other benefit to this design add , on the older cars and trucks if you bypassed this you had to readjust your timing so you motor would not ping or get a detonation knock under acceleration

98 chevy 350 5.7L how to change the carburetor

it is not a carburetor, it is a throttle body-disconnect the harness, the throttle cable and the bolts that hold it onto the intake-after you have removed the intake tube. It really is not very difficult, just take your time and pay attention to what you remove and where parts go for purposes of re-assembly.there is no fuel involved and it is a good idea to get a gasket for the throttle body to intake in case the original is damaged on disassembly.

1996 chevy silverado k1500 how do i replace the throttle position sensor? where is it etc?

the throttle positioning sensor should be right next to the throttle body area, near the throttle plate, which opens up and closes for acceleration, and de acceleration, with a wire connection to it, you will have to remove the wire connection, and then remove the sensor, and line the new one back up, the same way you removed the old one, then recoonect the wire connection, start vehichle, and should run fine, if service engine light is on, shut engine off, and then remove the negative battery cable, for about 1 minute, then reconnect it, re start vehichle, light should have went out, you will have to reset clock, and radio functions again, hope that this has been very helpful to you.

How do you clean EFI ON A 4.3 V6 ON MY 1989 C-1500 2 WHEEL DRIVE

remove the air duct hose that goe's to the throttle body, then you can see the throttle body area, you can purchase throttle body spray cleaner from a auto part store, start vehichle up and let run, and while holding down on throttle so engine won't die, gradually spray the cleaner into the throttle body area, and continue to let engine run untill smooth, so that the cleaner that was sprayed has time to burn the excess off of the o 2 senors, if engine light comes on after this, shut off engine, and disconnect 1 of the battery cables for about 1 minute, then reconnect the cable, and start engine up, light should be out, but later , i would hook up a code tester to the aldl under the instrument panel on drivers side to make sure code # from the light being on was removed, hope that this information was helpful to you.
