PONTIAC GRAND PRIX SENSOR PROBLEM

1996 Pontiac Grand Prix • 236,000 miles

Generic DTC P0134 and P0300 I know its oxygen sensor and random misfire. Could the o2 sensor cuase the misfire. If so do I need a new sensor?

I doubt the O2 could cause a misfire, check fuel pressure as well as normal ignition checks, plugs wires etc
