Engine ping under light throttle

First question. how many miles on the car (carbon build up)? Do you have access to a scanner with data access to see knock counts? Are you sure it is

First question. how many miles on the car (carbon build up)? Do you have access to a scanner with data access to see knock counts? Are you sure it is knock and not something else like an exhaust leak, not common on this car from what I've read but have had some pin hole exhaust leak that can sound like pinging under part throttle load.
