Hi guys,
CEL came on recently in my Liberty and at the same time, engine began running sluggishly when cold/accelerating (then would gradually start running OK as I drove). Diagnosed the CEL and got the following:
P0300 (multiple cylinder misfire)
P0152 (O2 sensor shorted to voltage)
Anybody think these are related?
I already replaced all 6 spark plugs...running exactly the same. Any advice on what I should try next?
Thanks in advance--
