Maybe, but then it gets back to the correct position? It's fairly difficult to reproduce and it lasts only a few mins, but could try to check visually maybe?
Have a run with the engine cover off, then stop and look, could I see something (if I can successefully focus something with all the rattle)?

Hoestly it doesnt seem to be an injector to me, but I cannot make my head around of another possible cause. :evil:

Fuel filter - nay
EGR? Don't see why, even if the dealer last time told me it was rattling a bit more than normal, but not to worry about it
lift pump - just replaced
something to do with the air intake?
A vacuum valve remaining closed / open after being kept strongly so for a while by the acceleration? That should cause simply non working turbo and I should hear the turbo noise being wrong.

All assumptions here, I am honestly young and unexperienced so you're probably right thinking about the injector. May get one from Ade to check, but they are a bitch to remove and I need the car every day.

Ah, I just thought - what about these swirl valves? I know they give a lot of problems on Opels but I've not heard of any on PSA (Apart from the actuator rod snapping) but there's always a first time...

Yeah, I know I'm just chucking wild ideas in here but I'm hoping someone will come along and say it's either worth a look or I need my head examined :cheesy:

What should I check about them? Only the movement?

The normal check is just to watch the actuator rod with the engine idling, then rev it via the TPS & make sure it moves.

I've still got my old set of injectors - one was definitely faulty, another suspect, but the other two were OK as far as I can tell.
Don't mind sending you one/two for the cost of the postage if you want to try them.

Suggest you do a leak-off test first to see if you can confirm the diagnosis.

I think I saw a youtube video doing it, I'll check. Very kind of you sir regarding the injectors, I'll do a test first if the problem persists, but I'm really busy with exams right now.

No problem. Just let me know if you want them, whenever you're ready.

Did it today again after a floored throttle 15mph to 55mph acceleration.
I stopped and opened the bonnet, the engine was vibrating like hell. When I'm at idle, in normal conditions, the intake rubber tube in front of the DW12 engine is solid in position, while the engine moves a little. When this foult appears everything is vibrating very strongly, I'll take a vid someday to let you see, the engine wants to escape from the bonnet!

Sounds very like mine was - if it's the same problem, the engine speed also becomes unstable at idle.

Do the leak test.

Do the leak test.
It's difficult to do the leak test cause the engine stays in that state for a couple of mins only.
revs at idle are stable even with a/c, but power under 1500 rpms isn't (only for the 5 mins after the acceleration). over 1500 everything's ok. I'll talk to the mechanic and fid out if we can easily and cheapily diagnose this. At this point a faulty injector seems probable. How much for the shipping to 32100, Ita, mate?
I'll throw in half a bottle of injector cleaner.

I've no idea. I'll get some dimensions & weight.

Anybody recommend a way to ship it?

If shipping is too much (shouldn't be) you could just ship them to Ade who'll ship them to me with my next order - I'm organizing a huge shipping from him for the italian coupé club - 15 wheels, an engine, something like 6 strut braces, various other parts. :shock:

Well, an injector weighs 530 g. Package would be 30x15x5 cm. say 1000 g.

I dont know how shipping prices are in the UK. But I guess shipping to Ade will be cheaper, I'll ask him.
