add some good fuel treatment...ZMAX... use a different brand of gas..


My old Tahoe was doing that one time, it would also do it at a steady speed very light throttle, I checked the EGR valve to make sure it was operating properly, and it was, so upon further inspection found out the intake gaskets were starting to leak internally, typical vortec, replaced the gaskets and the pinging went away.
