#1. Brake power booster vacuum line.
#2. The brown vacuum hose from the injection pump the fuse box area.
#3. The primary vacuum line from the vacuum pump may have been broken, if every thing went wrong.
#4. Reversed vacuum hoses.

You need help ASAP.

Question:
What did they do that took two hours?
The turbo line is a one hour job, start to finish.
Did they clean the engine compartment?

Something sounds fishy here:
There may be reason to mess with vacuum hoses on the passenger = right side of engine, but not the driver side.
If they power washed the oil off, you could have a bunch of disconnected or broken vacuum hoses.
