My T-Bird is bone stock - it knocks at WOT on ANY octane above 3000 RPM! It is fine at part throttle on 89 octane. Car is fully tuned up - just cleaned the EGR ports, and ran Sea Foam thru it - didnt matter! Also cleaned the MAF, cleaned everything!
I have personally never seen a computer controlled Ford that didnt knock at WOT. I am surprised this isnt the #1 topic on the forum!
I am looking to change to AWSF-22C plugs, but cant find the damn things!
Would like to try the Octane plug mod - anyone got a valid link? The one above doesnt work anymore.
