yaris does sound like a little buggy. perhaps that is where the little buggy sound comes from. it is nothing like 'real pinging' you'd get from a crappy 1981 chevy citation climbing a steep hill

Most definitely not. It's just a very light rattling noise. Got to listen for it.

On really unusually lugging mine down, on occasion I've heard about three distinct knocks (still on the light side) before the ECU retarded the spark.
