Answer
The throttle switch is part of the IDLE SPEED CONTROL MOTOR (ISC). If you have adjusted the small idle set screw on the side of the throttle body to increase your engine speed. You need to contact me. You will need, If necessary, Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
