On my recently aquired 96 Deville, I experience heavy detonation episodes during intermittant heavy throttle applications. This detonation occurs on one out of every ten heavy throtle applications. It does not matter if it is a WOT or one half of a WOT. It is so unnerving that my reaction it to take my foot right out of it. One one occasion the detonation continued into the subsequent up shift.
I suspect a defective knock sensor. There are no current codes. I do get a Service transmission display on the DIC with the related service engine soon light. I am running 93 octane.
Has anyone ever experienced anything like this?
