I wish they would do away with vacuum operated parts of the engine! Engines should have one high fidelity vacuum sensor and the readings from that, fed into the ECU, would then tell the other parts that previously had their own vacuum sensors what to do. That way, no one has to do smoke tests to tract down hairline cracks in fragile vacuum tubes. But I guess that is too logical?
