When my engine is cold it doesn't ping, whent it's at about 120 degrees it starts to ping just a little bit, when it's at 205 degrees it pings non stop. I just adjusted my timing 2 days ago and it's right on 8 degrees which was the factory specifications. Should I take my timing down to 4 degrees?? Do you have any other ideas as to why it pings when cold but when the engine is warm I can look at the gas pedal and it will ping. It's really starting to tick me off.
