    You have to use your eyes and fingers to inspect vacuum lines. Look for cracks or loose fittings. I'd check the intake system for gasket leaks, especially around the joint of the intake and the cylinder heads. also check around the throttle body.
    FYI, a O2 sensor code for the sensor being out of range, for instance, means that the signal is out of range. That is often caused by other problems, not that the sensor is failing.
