When I accelerate about 1/2 throttle or so, I will usually get a slight bucking along with a very light ping or clicking type of noise. If I go WOT, I don't really even notice it at all. I'm only using 10° timing.
Also, I hear a hissing type of noise coming from under the car somewhere while accelerating. I know it's not an exhaust leak, could this be catalytic converters?
Could both of these noises be something to do with the cats? It's really annoying sometimes.
