spark knock
it knocks at about 3k and above in accleration and i beleve it knocks in the same range in deceleration, dont know the timing (just bought the car), 93 octane, autolight plugs (not plat), msd wires, and it has a fairly new distributor but i dont know how old or new it is, looks to be a stock replacement. 120k to 125k miles on the car.
