As i just found out, you never know what your vacuume lines are doing unless you check them, all of them.
If even one vacuume line is leaking or disconnected, it can cause rough start/stalling issues....
In my case, the vacuume line that controlls the fuel pressure regulator was not connected... and this caused the car to run WAY too rich at idle... making a rough start and stalling at every stop light in town...
Even if all your lines are ok... the FPR itself could have a punctured diaphragm... which messes up the fuel supply as you can imagine.
It could be something more expensive... but it's always best to check the lines first, just to be sure. I was ready to replace my turbo... but it was just a $1 10min job!
good luck
