Major 01 Jetta Problems
 

Ok so I drive an 01 Jetta, and I'm having major problems!!
1) My turn signal sound won't stop clicking even when the turn signal is off
2) My car won't start correctly, I have to hold the key in the start position for about 45 seconds to get it to start.
3) When the car does start it shakes really badly, and sometimes just shuts off
4) Doesn't idle properly
5) Today I was slowing down for a light, and it felt like my car shifted down into first and then wouldn't shift out to speed up when the light changed.
6) Also my check engine light, won't go off

So I am taking it to the mechanic tomorrow morning, but if anyone else on here has had these problems please let me know.(I am just worried as to how much the repairs are going to cost) The car is an automatic with 92,000 miles on it!!
