Replace and Reconnect the Things Rightly
Now the last step is to replace the air filter cover and make it secure by tightening the nuts you removed. Place back the electrical connector into the socket at its earlier position. Then, at last, connect the negative battery terminal in the engine.
Now the idle air controller is okay and you can start your vehicle back.
