im not really sure. the bpt valve is supposed to allow manifold vacuum to the egr to turn the egr on when there is sufficient backpressure in the exhaust and load on the engine. try restricting the exhaust to create backpressure (restricting, not completely blocking) and see if the car shudders or dies. if the car does, the bpt and egr should be working correctly.
