Is there anything besides a faulty Oxygen Sensor that will set off a Code 21
on a 96 with a 5.2 standard 5 speed? The Exhaust was replaced and I
replaced the 2 oxygen sensors but still bringing up this code.

This might be wiring and ground related, where is the ground that relates to
the dashlights as I am having this problem also and have not located the
ground position. Thanks.
