Electrical problem
2003 Ford Expedition V8 Four Wheel Drive Automatic 74000 miles

what would the problem be if I drove with faulty oxygen sensors? And could the oxygen sensors cause the engine to misfire? And can the octane on the gasoline cause an engine to misfire?

Do you
have the same problem?

The oxygen sensors if failing will cause your engine to run rough and give you horrible fuel mileage, and will cause the vehicle to miss.

Too low octane will cause a engine to miss also.
