OK, I've had my car, my first stickshift, for about 4 days now and I'm getting better. I'm fairly comfortable with most things, except this one thing. Say I am going along and there's something ahead so I need to slow down fairly quickyl. So I pop it into neutral and just coast and use the break. But then it turns out that maybe the light changes or whatever in front of me goes away so I can start accelerating again, so I need to pop it into the appropriate gear for the speed I'm moving. When I push the clutch down, pop it into gear, and then start to gas it the car kind of shakes and the engine makes it sound like I'm not doing it right. What is the proper procedure for doing this? This is most notable when I pop into second such as when turning in a residential area. Any tips would be much appreciated!
