Cleaning EGR passage

When my Corolla did not pass the emissions test, the mechanic wanted to clean the EGR passage. When I apply vacuum to the EGR valve, the engine dies. Is there any benefit to cleaning the EGR passage?

If you pull vacuum on the EGR valve and the car dies it shows the EGR ports are open. There maybe some carbon in the system but it is not blocking the EGR system. He is tring to sell Maintenance?
