Poolman-I would also inspect the suction jet pump. That is the Venturi device that's plugged into the intake tube at the F connector. The thin hose is a vent for the fuel pressure regulator. The thicker hose goes to the suction jet pump that increases vacuum (above manifold vacuum) to the brake booster. If any of the hoses are split, if the device is cracked or damaged or if the vac hose to the IM is not attached, etc., you would have these symptoms.
Of course, any of the above would not cause your trifecta but it caused my brake pedal to be low when my suction jet pump was not working right.
