Hello, my name is***** and i will do my best to assist you.I am going over your story now and will reply back soon with some info,thanks!

vacuum is definitely the issue, we can start at the firewall to the engine and see if the lines came loose or cracked, this is a very common issue, here is a layout of the parts involved.

here is the vacuum diagram. hope this helps. if the lines are ok the issue can be the head unit in the dash.
