do you have check engine light on
you need to scan for codes
and check that issue
I would check air filter and check it for tune up
check fuel fill cap
before
oxygen sensors are like spark plugs with electric wires in them installed on the exhaust system before and after catalytic converter
unplug the wire and remove the sensor
