Hello everyone. I hope someone can give me some advice on my car.

I am gonna take it to my mechanic anyways. But it would still be good to know what could be wrong - to kinda get an idea of how much it could cost, if nothing else :).

So what sometimes happens with my car is: I feel like it has a somewhat jerky acceleration. I feel like it is hesitating and jerking ever so slightly when accelerating. This could also be due to the roadways being fucked (Roads are crappy where I live :)) So its kinda hard to really put a finger on it..Anyone else noticed anything similar with their car?

What would also happen occasionally is a big jerk when accelerating. It feels like car lost all its power for a split second..It just jerks violently but then continues to take off. It would sometimes only do it once/acceleration, but other times it would do it 2-3 times. Some days it would happen a lot, other days it wouldn't happen at all. No check engine light or anything on so I am not sure how I am even going to explain it to my mechanic...anything similar happened to anyone? Could it be the turbo?

Then the last problem is with the AC. Temperatures are rising in my country so I noticed the problems with AC as well. Its whining, leaving out weird noises of air passing through somewhere...But whining is what gets me. Its so annoying. Didn't used to do it. It also doesn't do it when heating, only doing it when cooling. Noises also stop if I turn the AC off... Probably its a compressor on its way out?

Any help would be appreciated.
