Injector rattle on lift off?

[JTaylor2005]

Alright guys

I have had this since I bought the car but never thought much of it. Whenever I let off from full or near full throttle if I let off quickly I get like a short burst of what sounds like the injector rattle. Any ideas what could be causing this? Having been for a proper drive listening to it im pretty certain its the same noise as the injector rattle just louder and for a short burst.

Any ideas?

Thanks

Could be many things, dying aircon or alternator pulley clutch, tensioner, tired injectors, turbo starting to leak oil... Shouldn't worry about it unless it gets worse.

What condition is your bottom pulley in?

[JTaylor2005]

Injectors have been changed although they still rattle anyway with the 076 ones -_-
The pulley was changed but for a second hand one that had only 10 miles on it or something like that.

Will have to properly have a search tbf

So having done a load more driving I have noticed something weird as well. If I'm accelerating then snap the throttle shut then the rattle happens as I'm right near being fully of the pedal for a very short burst of noise.

If I however stop lifting off at that "sweet spot" the rattle will continue for as long as I keep my foot at around the 10% throttle point haha. So strange.

Having changed the oil today and put some good quality shelll stuff in the rattle seems to have numbed down quite a lot :S It has gone from a harsh sounding rattle or a dull rattle. A lot easier to not notice as well when driving normally. I have no idea what it could be haha

What oil type mate?

Gone for shell helix ultra 5w-40 mate.

Sweet cheers mate. Last 2 times I have used the Peugeot recommended Total stuff but i'm not sold, doesn't seem like the engine likes it very much.
