Hi all I have a 99 v6 auto Stang with a newly installed set of Autolite platinum plugs and a set of Autolite Professional wires. It pings on acceleration any ideas on what could cause this...? Other than this it runs fine and starts good ??
The combustion chamber might have a lot of carbon buildup accumulated from lots of slow RPM stop-&-go driving, etc.. You could try & clean some of that out with combustion chamber cleaner (mixes with the gas)
Also how clean is your air filter?
Finally try some higher octane gas & see if that helps
