light pre-ignition or pinging will sound kinda like theres coins jangling around inside the cylinders. you can hear it easy enough with the stereo off.

Best example, older Ford Laser fitted with mazda engine cu cu cu cu sound when taking off under load more pronounced when hot days, yours should have knock sensors my rb does when it gets close to the point of it going to happen timing gets backed off. In my older cars that didnt have mechanicals suited for unleaded some times even when fuels a bit dodgy on a warm day it would ping its head off, (might have been that high compression shaved head i had, a thicker gasket did the trick even if it went a bit weaker) go to another brand servo put some high grade fuel in no more pinging, so there is a few factors to consider. If yours does check your sensors< still got factory management? If you dont hear anything your probably ok but if your worried go to a good workshop as they have equipment that would show if its abit out

yeah listen to old magnas going up a hill on a warm ( any temp really ) day...bit like shaking a jar with a couple nails in it.

Yeap some sort of metal-on-metal sound. Like shaking coins in a tin. If someone can point it out to you while a car is pinging, you'll know straight away anytime it happens in the future.

Ping = detonation, which is fuel igniting in the cylinders before it is meant to. In other words, uncontrolled fuel ignition, ie. bad for engine.

You can tell if your car does it from the sound, but also from the orange dash light flashing on and off. If you have a pfc, then you can set the hand control screen to show pinging as well - peak hold and present reading.

Its sometimes also called knock and pinking.
