A leaking fuel pressure regulator is the most common cause for a rich condition on the Olds Aurora 4.0L V8. -------------------------
A malfunctioning oxygen sensor can cause the engine to be low on power.
Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing. If an oxygen sensor is malfunctioning, it could cause idle problems.Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing.

Oxygen Sensor. Or the Knock Sensor. Or you could check the plugs for faults.
