Hi, I have a 99 Taurus Vulcan 3.0. Runs great excepting the "ping". Went to Ford, carbon removed, MAF, injectors, cleaned, spark plugs ok. No chance !
It pings like hell when the engine is heating, but only when i push the gas. Nothing when i run constantly speed the highway.
Doesn't work even with 94 octane.
What should I do?
Thanks a lot.
