Les, If the control pressure regulator vacuum outlet port is connected directly to the engine manifold thereby bypassing the thermal control valve you will experience an over enriched fuel mixture condition after the engine reaches operating temperature. This can cause an irregular idle, poor acceleration, high fuel consumption, increased emissions or any combination of the above. The DeLorean vacuum lines are not easily identified and are therefore routinely incorrectly routed or disconnected by owners and or service personal not familiar with the correct hose routing.
