unusual engine nose

What is your question?

Car is getting stuck at around 1100 rpms and makes a sound as if my foot is slightly on the gas when my foot is off the gas or im braking the sound stops when i fully brake and am not moving, any ideas of what it could be. it only starts making the sound when i reach lower speeds and the sound will stop if i press the gas a little and will stop when im fully stopped

How long has your 2011 Mitsubishi Lancer had this problem?

a few days
