Dear J. A. Knapper
Thank you for your suggestion. Let me update you (and copy the list) with a
partial solution fitting your comment.
I gave up on the dealers who recommended I switch to lower octane to stop the
pinging. Last week I had it at Kenny Brown Motorsports in Indianapolis to have
it lowered (which really helped the swaying ride problems mentioned on this
list) and mentioned the pinging. They think it is a loose exhaust manifold -
not pinging at all. Amazing that the dealers couldn't catch that, eh?
As for the swaying, my suspension cams had worn and my shocks had been
tightened too hard, causing the shocks to be loose because the mounting
threads had been worn off. Brown replaced all of it and it rides wonderfully
now. The dealers had told me to get used to it because "It's a truck". Ha.
So your advice about the manifold is timely. I will use that when getting it
fixed, as soon as I can find someone local to do the job (NOT the dealers).
Thanks again.
Jack

I have been pleased with the quality overall. I have a '97 F-150, V-6,
5-Speed, 25k miles, I put it in the shop to have the clutch adjusted
because reverse was grinding, and to have a rough idle looked at. I
came out with a new transmission because the reverse gear was shot,
and they updated the engine's computer data. Overall, I am rather
pleased. I had a loaner car the whole time, ('98 Taurus w/V6) and they
kept me informed the whole way. I love the truck, and I'm looking
forward to my next one. A '99 F-150 in April.

Second try:

I have a 97 F350 crew cab 460 5spd 4x4 SRW with 3,500 miles. In the
last month or so, this truck has slowly started pinging and knocking
on warm days and appears to lose power when doing so. I am hauling
very little in it. This knocking is loud enough that passengers are
commenting on it. My old chevy with 200,000 miles never knocked this
loud.

If anyone has had similar trouble, please give some hints on how to
handle this.

OK,

I'll take a stab at it (guess)!

Here's some things to check:
1. Check for computer codes (does Ford have a way for the owner to check
codes)?
2. Check for EGR operation, if it's inoperative, you will get pinging
3. Check the injectors, if one is leaking, it will indicate to the oxygen
sensor that you have a
have a rich mixture, and the computer will lean the mixture to try to bring it
back into spec, thereby causing pinging.
4. A malfunctioning oxygen sensor may be giving the computer false
information, causing a lean mixture and pinging.

As best as I can recall, the big three mechanical problems that caused
pinging were:
Malfunctioning EGR
Lean fuel mixture
Overly advanced timing

This truck is still in warranty, isn't it? If it is, take it back to the
dealer and make them fix it!

Best Regards,
Robert Stout

The 97 460 still has a distibutor and could be simply out of time.
Being as it is still under warranty insist they check the timing as
well as the other suggestions made. When I turned in my 97 F250 with
a 460, it didn't ever ping or knock with 13,500 miles.
