For the past couple of days I noticed that my gauge is like really sensitive. Instead of the needle moving slowly it now moves fast. Like when I am listining to music or having my turn signal on. And when I turn off the car the needle ofcurse goes to zero but it does it so fast that the needle actually bottoms out and bounces. Whats the deal

 

i dont know about the needle bouncing when it shuts off, but if it seems more sensitive than usuall maybe your alternators takin a turn for the worse and so there is just more fluctuation that you are seeing.

 

I would definately say the gauge didn't all the sudden get more sensitive I would say that your power source is acting in a different manner. Keep an eye on the battery.
