Hatchback
if it drives normal except when you let off the gas the rpm jumps then it is a map sensor
09 chevy impala rpm jumps up and down
A cars tach jumps and runs with engine rpm.Sometimes if it jumps and changes engine sound,the throttle position sensor needs changing.If it jumps with no engine speed or sound change it means your alternator is going bad.
Probably hitting against the glass
All signs point to your transmission. Get this checked out ASAP, otherwise your car is going to get suck in one gear, and you will blow your engine, let alone get stuck who knows where because your car won't move.
I think you mean when your mum jumps
Not sure what you mean by "jumps". Maybe you need new struts or shocks.
Needs new speed sensor or if it has a cable to the speedometer it needs to be replaced along with the housing.
needle means needle same as English its said hari
coul be the map sensor
If it literally "jumps", it's a bad motormount.
