Spark knock, How to get rid of it?

Thank you. I have an Actron scanner that will show live perameters. Do you know of any numbers to go by? OR what I need to look for on the fuel trim? Will the KNOCK sensor throw a code out? ... I do not have any lights on , on the dash. Thanks CM

Have someone else drive it and watch the spark advance and knock sensor activity. Before you get to far into it.......2010 and 33,000 miles- Check your warranty book(s)- may be covered under warranty Federal emissions warranty on some items goes past the standard manufacturers powertrain warranty of 3/36..............back to the other stuff--LTFT should be close to 1.00 +/- .03 check coolant temp.-should be between 210 & 220F fully warmed up.Any aftermarket mods?

No mods yet. All stock. Bought Jeep used w/ 23000miles. Thanks for the info I will check it out.
