The plugs that everyone's using are Autolite 3923's and the t-stat is a
Robertshaw 755-180. The plugs are one step colder and the t-stat is 15º
cooler. Pinging is really hard on the engine and you should find a solution
as quickly as possible. Your dealer should check the belly pan gasket
first. One of the remedies the dealers have is to retard the timing by
flashing the PCM. That has worked for some and not for others. Retarding
the timing also degrades your performance. Once they do it they can't back
out of it. That's a word of caution for you. Good luck.

Hey Sean & Everybody,
I'm still running the factory plugs....i haven't pulled them and looked at
'em, either. Usually, i run Texaco 87 octane gas. On my last trip, to get
the pinging ot stop, i poured in some 'marvel mystery oil', and ran chevron
89 octane....at one spot 'fore i put the 89 octane in, when i was
accelerating to get on the freeway, it pinged all tehy way thru every
gear....i wasn't accelerating abnormally hard....and my engine routinely
sees
up to 3000 rpm. I'm going to have the dealer hook it up to the computer to
look at the rough idle/pinging when the body work is done...
How big of an impact does thermostat have on pinging?? i'm thinking of
switching that too...and what Autolite plugs will work best?? i can afford
them, and will go get them soon as i get a part number;)
TIA,
Mike

Dak-less till this next week:*(
