HAve you tried either raising the octane of gas you put in it or two trying some octane booster to see if that makes it less/go away. If so It might need to run on a higher octane fuel to not ping. My Uncle wasted a small fortune on a small block ford trying to fix this when all he needed was higher octane gas.

That I have tried. Even used the Sunoco 94 and added the Octane 107 Booster. Still the same. I am about to give up.

Where is the knock sensor located?

Don't know for sure. If it is a V motor there can be two of them tho. They are very picky about instalatiioon torque. Can't be too tight or too loose or they won't function properly. Need to pick up a manual. Check the links on the blue bar to the left or your local library.

Good luck and let us know, :)

Built up carbon deposits can be the cause of pinging/knocking in many cases. I'd try a good fuel cleaner additive and/or perform a Fuel Air Induction Service and see if that does the trick first.
