My car has 17000 miles.
My car has a manual transmission.

Based on your description, I believe that there could be an issue with the throttle body. I would recommend having the throttle position sensor inspected as well to determine if it is working properly. Once the throttle body has been cleaned and or replaced and the TPS has been ruled out, these issues should be resolved.
