Right gang...........all the bits I have are now on......I have a set of new injectors coming on Wed to throw in as well from Rentech.
That crankshaft pulley bolt though.....wowsers, that was TIGHT.....just proved the value of my brand new Milwaukee impact gun (the brutal 1300lbft one)
Locked her all up and had a quick tweak with the breaker bar and my nerves wouldn't stand it. Popped the impact gun on in its lowest setting and 3 or 4 hits from it (runs real slowly in the lowest power) and out came the bolt with no fuss to the belt. Mega.
Took the pulley off and OMG the core is basically hanging out of it.......EEEK!
Anyhoo.......new pulley on and torqued and after about 5 manual rotations of the engine (pulleys all still tight) the timing looks absolutely perfect. So as has been said, it can be done without re-timing as long as everything is locked up.
One quick question, I checked all of the aux pulleys etc with the belt off and none were making any noises, had any play and all felt smooth.
I only used the jubilee clip method to stop the tensioner killing me and that worked fine but I have noticed that on first start the belt is a bit squealy when turning the steering. This goes away after a minute or so.
Is the tensioner capable on its own to tension the aux belt or do i need to give anything a little tweak?

Its capable as long as its free to piviot on its mounting bolts they should be torqued i use silicone spray on the mounts so it can move freely.

Eugh............balls..............so I still have that weird squeal on full lock when the car is cold............I thought it was the crank pulley when I put marks on the inner and outer sections and noticed that they moved apart. I assume that wasn't a wasted job anyway?
Once the car is warm the squeal is gone but if i go hard on the steering, left, right, left, right etc really quickly it does get heavy :/
Going to throw in some AT to the PAS reservoir today as it is on or below minimum from what I can see
If that doesn't sort it, I guess I am looking at aux belt/tensioner/pulleys (replaced around 3 yrs ago with the timing belt) and after that, the PAS pump?

So i still have a bumpy idle...............yes, i know they are bumpy in general but mine has the Fstchip map on it which as far as I can recall..........had it idling at 1100 (can someone verify that for me?)
Anyway, I have been reading the workshop manual (heck, beats the news) and noticed this.............not sure if it is relevant or if anyone has ever seen it, but the symptoms sound fairly similar
WARNING: if the solenoid valve is jammed in the
open position this will result in an unstable idle
and the pressure in the manifold at idle will be
too high.

You can test it by removing it and connecting it to 12v.

You dont need to code them in or nothing fancy but nothing wrong with resetting the adaptives. Adaptive is the key here it has adjusted to run ok for the shitty injectors and you bang a nice new set in which will take the ecu a while to compensate for. Use the proper tools for the job if you have access to them, i bet most run s**t due to the throw it together and hope for the best method

Need clip to do it as far as i know mate. Not tried any other diagnostic.

Well, injectors should be here today and I will throw them in tonight.
I really hope it helps the bumbling idle as the stalling is real. Still idling at around 900 rpm. Can anyone remember what the Fastchip map idle should be? I was sure it was more than that.
Even after replacing what I have done already, I still have the hanging revs and stumble to below 500 rpm when I pull up to a stop, in traffic for example.
This morning was a killer as the motorway was a mess and just sitting in first gear, roll forward perhaps a car length and clutch back in, the revs sit at perhaps, 1300-1400 rpm and then just drop. If I am starting to move off again at this time its an instant stall.
I have been doing this route for years now in this car and never remember it being so bad.
The throttle body has been cleaned perhaps a few months ago as one of the first thoughts.
Still leaning towards the map sensor @bloke if the injectors don't help? Timing was as far as I could see, perfect (cam tool loose in the slots when crank pin in)

Air leak is a fair point as I decided that the breather gasket was a wee bit hardened when I was doing the other work so have ordered a replacement one of those, not sure how relevant that may be.
All I have is RSTuner fella. Not ideal I know but it looks to be able to spit out quite a bit of info albeit in a graph format.

You can datalog with RSTuner.

Thanks @JamesBryan
Ok, have to do a quick run out now to collect the injectors (yay) so will have a punt at logging what I can.

When you've selected all the parameters you want to log, you have to click the blue live data button at the top for it to start. I made the mistake of wondering why it wasn't working before now ?

So..............of course it is hard to replicate the issue WHEN YOU WANT.....lol
But, it did most certainly do it when I pulled up at the house at the end. Not as severe as say sitting in stop start traffic for a while but exactly the same behaviour only less pronounced.
Drove in, all seems well.............pull up on the drive and you can see the vehicle speed getting to 0. Sits for a few seconds with the rpm at a fairly normal level (this is usually say, 1100 when it is severe) and then the revs drop and then recover.

I don't know what much of that means ?
But, is the ignition advance meant to move around that much?

lol.....me neither.........it's all witchcraft 
no idea with regards to the ign. advance..................does remind me that this car has a EuroCarParts knock sensor on it.
I remember one very special night............i managed to completely snap the original one off and had to replace it. Almost sharted at the price of a genuine one.
Relevant?

Did you try a map sensor on this?
The way it rises at the same time as the engine speed dropping could be suspicious.
Mine reads 380mbar at idle.

I did not.................despite being told a few times to do so
I am a bit of a tit like that
Injectors tonight and then I will see what is what. @Louis offered a second hand one so might take him up on that as they are injector money for genuine.
I am also now considering a new knock sensor from a decent brand. Can get Valeo from ECP for decent money with the XMAS code.

It could be that anyway or an air leak, i'm no expert.
Just with the way it moves out of sync with the throttle.

I'm not even sure if mine works mate! I'm having similar issues but not stalling at all.
They were original bought from euro car parts or carparts4less as 431745200 is unique to that company.ACH WTF
Bought 4 injectors from Renparts.................one of them is COMPLETELY WRONG yet labelled the same.
Correct on left. Wrong on right.

Has the incorrect one been opened and then sealed with white tape?
The one`s I got from Renparts just had 805001446001 on the label.

Mine were packaged the same as Steve's.

Renparts are pretty good normally. I reckon if you ring them they will send you another one out asap.
I have previously had an issue with them around a used part and they were really good about it.
It was me that had a good used map sensor @jinjur
Keep at it mate. Sure you will get it sorted soon. Then all this hassle will be forgotten about. Be interesting to see how it is once you have four new injectors.

If it has been anywhere near ECP, anything is possible, as I commented in post 12 here, 2 weeks ago.

Seriously Steve......don't.....I am close enough to the edge here
Well.....they were all sealed with the magneti marelli stickers.....No tears. The odd one was sealed too but looking at the info on it.....while yes it is an IWP042.....it does also say PSA on it.....to me that is Peugeot.

Give Renparts a ring, obviously it`s not their error and they will sort it.

Spoke to Renparts earlier and they cannot understand but are arranging to send a replacement.
But.
I have just replied (in a nice way as they have been lovely tbh) to advise that I am actually not happy abut having ECP stuff near me at all...................I mean, I have a code for ECP that would have brought injectors within a smidge of Renparts price.............and I could have had them in a similar time frame as well and collected locally...............BUT................I did see the thread you mentioned Steve and chose to use Renparts.
And as mentioned..........it's not against ECP at all really, it is about end users abusing the return process and ECP not being as thorough as they can with returns etc.
I thought buying from Renparts would mean even if there was a return, it would be subject to more investigations than ECP
The fact that these have in fact come from ECP has completely shat upon my illusion that these were straight from Marelli
The one that is incorrect btw..............was actually opened and has been sealed shut with an ECP (IWP042) sticker......I can tell because of the dirt under the ECP sticker........the Marelli sticker underneath says IPM012. It was opened at some stage.
Am i being unreasonable here? Should i content myself with the replacement one? Maybe I should and just wise up. Eugh
I HATE CARS!
