Many questions to ask. I will go into further detail.

Just curious if it can be fixed. I don't really have the money available for a different car. We like the car it's just those issues. I want to try and fix it. Would it be better to rebuild the engine?

From what you have given for information , it sounds like the money you 'don't have' for a shop , may be wasted on guesses rather than accurate diagnosis. EVEN if you do the repairs yourself , it would be well worth having an experienced Volvo tech take a look at it! turbo repair/replacement alone may be in the thousands of dollars!! Good luck.

Thank you. I am really hoping this can be fixed without having to spend a lot of money. I appreciate the response.
