hi all, my 1992 liberty sedan has recently become very sluggish and losing coolant somewhere.
i replaced the fuel filter, thermostat, and oil filter aswell as checking all of the hoses for signs of cracking or splits over the weekend and also thought i should check the check engine light code, it flashed 3 long and 2 short which i think is the o2 sensor

could this be the culprit for all of the dramas i have been having recently?
