  8. Knock knock. Who's there?

    So my car decided to play jokes with me during my drive yesterday and I guess it really wanted the last laugh. Will have to remove the valve cover first and pray for the best. Hoping it will not require a total rebuild. No CEL and no DTC's and also going by the sound it is probably something...

    Questions about Knock control. Im runnning basemap 19.5/21.5 dual tune. .85 is the highest knock control that I have recorded.
