what is the throtle body ? and how do you clean?

Follow your Air filter housing back, the first sensor is the Mass air flow sensor, after that is the Throttle body, easily removed, make sure you have a new base gasket, use in my opinion, 3m Throttle plate cleaner, clean with a non scoring material. Reinstall. Remove throttle pulley cover. Remove inlet hose to air cleaner (ACL) . Remove fresh air intake between air cleaner and throttle body (TB) . Remove link between throttle pulley and throttle body. Remove the connector from the throttle position (TP) sensor. Remove throttle body from intake manifold. Move throttle position sensor to new throttle body. Tightening torque 2 ±0.5 Nm . Install the new throttle body on the intake manifold. Tightening torque 7 Nm . Connect connector to throttle position sensor.
