guys out there correct me if I'm wrong, but isn't ping just the sound of pre-ignition? If i'm right (and I'd like to think so), just move up to a higher octance gas. Maybe 89 if your using 87. I remember an old `88 honda civic I had used to ping really bad but it was because I always put 87 octane in it.

If the knock sensor was not working it shoudl trigger the check engine light. Theese trucks are intended to run fine on 87 octane... unless you have it chipped or something you should not have to run over 87.
Some questions:
Is the engine running hot at all? Are you towing a heavy load? Is the check engine light on? Does it ping all the time or only during certain instances?

It is not running hot. Not towing anything. And no check engine light. It pings every time i step half throttle or more. I do have the Superchip, and it doesn't pull up any codes.

Sounds to me like a possible problem with the superchip. In a car I have I got a chip for it that also made it ping even on Ultra 94. I got a different brand of chip and all the problems went away. I don't know how superchips works but maybe you could contact them about it? This is just a suggestion as I know a lot of people are happy with their superchips products..... maybe you got a "lemon" though. It may be a good idea to ask this in the computer tuning part of the forum. Maybe there are others with the same problem or a suggestion.

my 97 4.6 auto started pinging at WOT when it had about 130,000 miles on it. cleaned MAF, IAC, EGR and ran some throttle body cleaner thru. No more ping and that was about 20,000 miles ago. I think MAF was the root cause. Takes 20 minutes to clean. If you have F and N stage 2 oiled air filter for sure, clean our MAF first and see if that helps. replace fuel and air filters if the are doubtful. running higher octane gas is just treating the symptons instead of the disease (IMO). everybody has their favorite gas, but at about 70,000 miles i switched to chevron due to their techron additive.
