Hi there,

Recently purchased a 2006 Civic VTi. Ever since I've had it, i;ve noticed a pinging sound from the motor, usually under load either under hard acceleration or going up a hill.

My father in laws new Toyota RAV 4 does exactly the same thing.

I changed the fuel to a higher octane, and 95% of it went away.

Honda mechanics have noticed the ping, but basically I've been told that they can't adjust the timing, as its all set these days and to drive with the higher octance fuel.

Is it really a ping or with these v-tec motors is it someting else?

Thanks
