01 Pinging WOT only question
I've read many posts covering this topic and just wondering if its normally due to the fuel. The pinging only happens with my foot planted to the floor board. All other times it does not ping. Even when I accelerate in 6th when I should down shift, it does not ping. Also it does not ping under load up hills etc. Thanks in advance.

You could have carbon buildup in the cylinders causing an early ignition. The seafoam treatment will help clean out the cylinders. A lean condition will cause detonation also. A clogged fuel filter will cause loss of fuel when the demand is greater. WOT is the greatest demand for fuel you'll ever have. Most high HP guys (including me)will run a wideband which would reveal fueling issues at WOT.

Seafoam technique and links
Putting Seafoam into the gas tank will NOT de-carbon your engine. AFTER doing the PROPER Seafoam treatment using it regularly will keep the fuel system clean and reduce future carbon buildup.
Suck Seafoam in through the intake while engine is running, then stalling engine WHILE Seafoam is being sucked in. Let it sit overnight – a full12 hours. This will allow the Seafoam to soak thoroughly into the built-up carbon. Upon starting in the morning much smoke will emitted out the exhaust. This is the carbon being expelled.
Change the engine oil SOON afterwards.

Use high-octane gasoline – 91 (or 93 if available in your area). Use a quality gasoline. Quality gasoline has sufficient additives to keep your fuel system clean.

My car used to ping at WOT. After changing out the fuel injectors the pinging stopped.
The fouled injectors were causing a lean condition which in turn caused the pinging.
There are various reasons that your engine could "ping" at WOT I'm simply sharing my particular experience.
I hope you find an inexpensive cure. Be sure to share your findings with us.

Consider a catch can to trap oil before it coats the inside of your intake manifold and enters the combustion chamber. I would do that & seafoam. If the problem still persists, consider getting it tuned.

'01 had a number of changes including several software versions ....
Some are more prone to knock. You may end up requiring a tune.
I suffered the same knock issue on my '01 Vert until I had ECS tune it

I had the same problem. Put a can of Seafoam PLUS a 12-gallon bottle of Techron in the tank, then filled with Texaco. Took about a tankfull overall to eliminate the problem. First half tank, no change. Then I said to myself "Self, what about sloshing the stuff in the tank(s)?" Did that and within a half tank, problem was gone. WOT no longer produces pinging. HTH
