What does a Knock sound like??

[transient]

every once in a while when I drive, mostly when accellerating, I hear something that doesn't quite sound right. I'm not sure how one could really answer this question, but if anyone could, i'd be very grateful.

best description that I have heard is it sounds like metal playing cards being shuffled in your engine, I'm dealing with detonation right now and that is a good description.

Hmm... maybe it's time for me to have a tune-up. Damnit... I've spent too much at the moment already...

any ideas on what it would run me?

hey ca18 since its still being in the detonation mode record the sound and send it to me

Most 240's will knock, its just how they are designe. To an extent it isnt that bad. Pull your car in the garage and then let it idle and step out of the car and you should hear a light ticking noise every fraction of a second. Check your oil and try a better octane fuel.

hmm... i've also noticed that every once in a while it Idle's kinda high, like around 1000-1250 or so.
