First, it sounds like a throttle position sensor. However, if the check engine light has been on, there should be a code stored in the computer. Have the computer scanned to determine what code is stored. Most parts stores will do it for free. Once you get the code, it should identify where the problem is coming from.
Let me know what you find.
