O2 sensor head gasket.
I have also been getting oxygen sensor codes being thrown every month or so the check engine light typically goes away.
If its a coolant type leak.
If there s a head gasket leak then yes it could.
Oxygen sensor is just that it detects oxygen in the engine.
I hope they u changed the plugs but the blown head gasket will cause damage to the o2 sen and the cat.
The missfire is caused by ignition sys leak or compression problem the o2 sensor only reports the amount of o2 in the exhaust if it is fouled it can cause the engine to go ritch or lean and affect a lean or rich missfire so if you have a check engine light find out.
Oxygen sensor o2 what else could cause rich or lean codes replacement of a good oxygen sensor o2 is a common mistake made by diy mechanics all the time.
