Whys my VZ doing this?

[Vzille]

Hey guys,
Okay few question about my VZ Executive

1. Why does it putter away from stop start? aka stopped at lights then foot down to take off the putters away barely goes anywhere the finally kicks in and goes.

2. At gear changes fan belt seems to squeal, mostly on high rev gear changes. Why does this happen?

3. At 110km car vibrates and gets worse faster you go?

4. Between 75km and 85km doesn't know wether to change up or down?

Any help would be great 
