Hello, welcome. My name is***** will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

From what you are describing the issue that you are having is with the throttle position sensor, the throttle position sensor when failing results in the symptoms that you are having, this is also a common failure.
