Best way to do it would be to warm engine and use a can of starting fluid to spray hoses and vacum connectors, as you are spraying listen for the engine to change speed, when this occurs you have found your vacum leak. I would also be advisable to have a fire extinguisher made for garage or kitchen just incase.

The engine is idleing up its RPM to compensate for the added load of the powersteering pump kicking in when you turn. If it doesnt idle up, it will die, no mater which way you turn the wheels. Check the vacuum lines and powersteering lines, EGR lines, IAC lines, and intake hoses. Make sure nothing is cutting or pinching into them. Make sure you have no leaks from any of them if you do it could cause the problem. Can also be the power steering pressure switch or the Idle Speed Control Motor is defective.
