My check engine light came on. I went within a few hours of my light coming on to get it checked. The code came up and they told me it was a "mass air flow sensor". I got it replaced within a few days. Not even a week later, my check engine light came back on. I took it back, the same code came up. I'm not sure, what i should do. When i start my car and when i'm using my break, my car vibrates, and almost like bounces, so much that my steering wheel bounces.

Check the wiring to the sensor to make sure there is nothing damaged. Check for corrosion at connections.
