Detonation

[Need4Speed]

I've got a little detonation on 1 bar or so boost, just a couple of pinks. Is it possible this is due to ageing plugs? Car's done 59K and I've no idea how old the plugs except that they're no more than 59k:)

Yes I use optimax

so you haven't changed the plugs since you got the car? How many miles have you done?

Plugs sound like the likely culprit.

[Need4Speed]

They've been in there all the time I've had the car (a year/12k miles) It used to be happy to at least 1.1 bar. Still, 60K service to do soon, so I'll change them.

Almost certainly plugs then.

John, How can you tell this :confused:

[Need4Speed]

John, How can you tell this What, the pinks or the mileage, or the age of the plugs? The pinking I can hear

[Suprash]

How can you hear pinking, whats it sound like, and can you hear it normally over the engine noise......???

Sorry, have always heard the term 'pinking', so am curious !!!!

[Need4Speed]

Pinking sounds like a metallic rattle which goes away if you ease off the throttle. What happens with mine is that the ignition re-times to stop the pinking as I get off the throttle. Pinking sounds like the engine going "pink pink":p

Hence where the name came from I guess, Cheers.......
