I have some more information to add on the EGR. There are two vacuum transducers- one for the egr and one for the boost pressure. There is another valve called a boost pressure cut-out switchover valve that should a malfunction occur in the boost pressure control circuit, the valve vents the boost pressure and the injected fuel quantity is reduced. I think this is what is happening. There is a two lead wire going to both transducers and to the cut-out switch and to another valve right at the egr. What is telling the car to cut boost when the vacuum line at egr is plugged and how do I trick it into thinking nothing is wrong?
