So I have some weird noise. It sounds like detonation, but piston engine kind of detonation. From what I've heard, rotary detonation sounds different. I don't really know what it is, the only thing I noticed is that it doesn't happen when it's warm out or the engine bay gets nice and warm. Also the noise happens at really low loads, so I was thinking it was not detonation. I think maybe its a loose pulley or something, but not sure.



So i got on it a little more than usual today and heard the noise for a second and the power cut out real bad for that split second. I assume this is the knock sensor kicking in. A noise from, say a pulley or something, could trigger the knock sensor right?

When i got my ae the plug wire were backwards and it knocked, honestly if was so nasty sounding i thought it was the tranny. thats about the best way i can describe it, like a grinding noise almost.

I realized that it sounds like one of those clicky clacker toys, goipng really fast. http://quest.arc.nasa.gov/space/teac...ages/7.12b.gif

for me, it sounds like someone flicking a piece of aluminum foil :0

knock sensor only pulls 5 degrees of timing, prolly wont feel that

Orly? I wonder if I just let off without thinking when I heard a noise? Or is it something more sinister...

dunno. friend of mine came by with a weird clunking type noise, turns out the main pulley was loose!

would one of those chips off of ebay cause this

it might

ebay chips = worth as much as cow chips.
