Nope, no knock sensor, unless you add one of J&S's units.  No advantage to
higher octane if you're not pinging on regular.  Advancing the timing on a
car with a knock sensor could still make it perform better, 'cause you would
be getting your advance in earlier where it's not likely to ping. FWIW

ps  I should qualify--I haven't seen a '96  or a '96 book yet, but I doubt
that they have added a sensor. The engines aren't generally ping prone.
