Hi...I would like to assist you with your question. If you were told the throttle valve control module is faulty I would not be a big repair labor wise , but the part is pretty expensive. Its basically part of your throttle body where the air gets into the engine and has intake tubing connected to it. You can try and have someone remove it and clean it out with carb cleaner, this might fix it. If not it would have to be replaced Thanks, David contact me if you have further question regading this.
