Answers :

The Code 401 is saying there is no flow to the EGR. The other 2 codes say both sides of the engine are running lean.

You can look for Vacuum diagrams for your model car and get some photos to see routing.

What you might do is use a digital camera and try to find a car in a Salvage yard with the parts you need attached. Photo them and then take the hoses and solenoids off the Salvage car and add them to yours.

This would be the cheapest and most complete way of doing this. Unless you can find a shop willing to install used parts to your car. Now some Body shops routinely use Salvage parts for Bodywork. One may be willing to do a little mechanic work to help you. They do mechanic work to replace broken engine parts from accidents, so working on engines is just part of the job.
