Got a oil change with the filter. Also replaced number two 02 sensor.. week later it starts knocking then turns into pinging. Now just flip a coin one day it knocks and other day it just pings and some days nothing. Now I live by the mountains and when I go shopping down from here it's not so bad but soon as I get home it starts in again. I have checked everything. I'm lost for words and haven't a clue what's going on.
