I made a temp blank for the egr and no change. this morning I have found a small split in the vacuum pipe going to the turbo actuator so iv changed that and manualy pumped some vacuum in to it and its moving the actuator but still no change iv exhausted all my thoughts now so I think it will have to go to Honda and be put on there machine like you suggest we did run a scan on it last night and nothing came up.F6HAD said:
I have 1 leaking injector due to waiting for new seals but I didn't think that would cause this would it ?

No, it would still run ok with a leaky injector seal.
Plenty of other places could perform diagnostics on your car... A diesel specialist, a Bosch service centre (there's one of those in Church Stretton) or any garage with a Honda Diagnostic System (which are pretty cheap and common things) or any garage that has, say, a Snap-On machine with the correct Honda key. Just make sure whoever does it has access to such a machine and knows how to use it. I certainly wouldn't take it for granted that all Honda dealers understand the i-CTDi, as it's a bit old now and maybe not many Honda techs are familiar with working on them!

I went to Honda this morning to collect the seal and they have informed me the live data will probably not show anything up if its not putting any codes up and the boost pressure valves are working anyway so I'm stuck again the chap has offered me a replacement turbo so looks like I need to swop them over again
Live data will tell you what the ecu is requesting and what the engine is delivering. If it's a fuelling, intake or boost problem.. it will help pinpoint it.
Honda dealers really do have some muppets working there.

See, that's how useless Honda dealers can be... sounds like he didn't even consider running HDS interactive test routines which would have shown up which sub-system was failing, but simply offered a simple OBD2 scan to look for stored codes? Waste of time!piglet1 said:

Ok so I need a HDS test ?
Hds or a good Bosch or snap on diagnostic, I would suggest all dtc scan, does seem like turbo, a vaccum pressure test will be useful, you could have faulty turbo or incorrect ecu, have you checked airbox pipe for any signs of oil not a diesel exert so those are where I would look.

As Saj says, HDS or equivalent (interactive, target-setting) diagnostics would be ideal. I suggest you at least speak to the Bosch Service Centre at Church Stretton to see what they can offer.piglet1 said:
Even something that displays real-time data Vs map target would be better than simple code reading. I have a OBD2 scanner with a real-time display capability for several parameters (including boost and MAF, etc.) BUT (and it's an important but) it cannot display the required target data, so you cannot see direct evidence of where the sub-system performance is falling short. However it will show changing MAF and boost figures.

iv just spoke to a Bosch service centre and explained whats happening they have advised me again without any management lights coming on its very unsightly they could pick anything up

Well that's disappointing too! Makes you wonder what is the point of specialists...piglet1 said:

Iv explained the situation to 3 separate garages one Honda one Bosch and one independent and asked for a live data diagnostic and all 3 have said if its not putting the engine management light on or throwing up any codes its very unlightly the diagnostic will show anything upJon_G said:
I disagree not all dtc throw a light, I did full dtc scan and there was no light on dash, there was 3 dtc stored, one was ecm / pcm failure due to battery disconnect, I agree they were low level codes but you may get clue if there any

This is nonsense. I don't own an HDS, but I have borrowed one from member Freddofrog (who is currently on holiday) to extensively run tests on my engine... it enables targets to be set (so, for example on the diesel, fuel pressure, turbo boost, EGR %, IMRC position) and then monitors how accurately that engine sub-system achieves the set target... mine failed on fuel pressure, despite no previous error codes in this regard.piglet1 said:Iv explained the situation to 3 separate garages one Honda one Bosch and one independent and asked for a live data diagnostic and all 3 have said if its not putting the engine management light on or throwing up any codes its very unlightly the diagnostic will show anything up
I'm not making this up, I've actually done it and have previously posted pictures on the forum. It can also log in real-time engine performance against ECU-generated targets as you drive around.
I know that Fahad has his own HDS (which he uses regularly in connection with his work) and can back me up on this.

is vacuum pump on FL engine compatible with PFL controls ?
is the vacuum pump connected up and working ?

Jon I believe you and don't get me wrong I'm grateful for any and all advice and I'm trying things as I'm recommended them its just the 3 garages I spoke to didn't think it would work and there for didn't want to do itJon_G said:
however a small garage round the corner from me has told me to drop it off with him tomorrow and he will look at the live data for me for free and see what comes up so hopefully we will know more tomorrow

its connected and working I did wonder if the pumps where the same but Jon had a look for me and they both have the same part number so are the samewoodie said:

It is like hitting a rev limiter, as you said.
Good luck with the garage tomorrow. Let us know how you get on.

It sounds like none of them can be bothered getting involved. Any decent mechanic will be able to get to the bottom of it mate, it's going to be either an intake or boost problem. If not the egr then possibly the intake flap.

To an extent I can understand them being reluctant. This may not be a true 'fault', but could well be an ***embly error that diagnostic equipment may not find... and what's needed then would be a proper technician who is absolutely familiar with all aspects of the i-CTDi engine (ideally with a working vehicle for comparison) as opposed to the usual workshop fitter who's diagnostic abilities stretch only to connecting up the computer to the car.
piglet1 - did you ever contact Goodluckmonkey about these problems? He fitted a later engine (from another model) into his PFL Accord and had to swap a fair number of bits to make it work.

I dropped it of at a garage this morning and he's going to take a look for me so hopefully a fresh person on it can find something
as far as contacting Goodluckmonkey no I didn't but iv just messaged him now

is there any way of testing the fsvF6HAD said:

Hopefully you used your original FSV?piglet1 said:
Not as good as using HDS, but you should see the bellows linkage moving on the IMRC as the vacuum is modulated by the FSV. If you pull the electrical connector off the FSV then the IMRC will adopt a 'safe' running position (but you will get an error code, something like a P2004/6/8)

He has his own HDS and can obviously advise you on diagnostics, etc as well.piglet1 said:

right todays update absolutely sweet F A live data apparently didn't show up anything out of the ordinary the imdc is moving so I'm ***uming the fav is working ok and yes its my original one
I just had a random thought that the rag I put in the exhaust when I was degreasing the engine bay may have not totally been removed and was suffocating it when you rev the car but iv removed the exhaust and still no change that would have been far to simple

No rags in the intake pipework then?piglet1 said:
I'm not sure how helpful it'd be, but I'm planning to be in Shrewsbury this evening (here... https://www.theredbarnshrewsbury.co.uk/) so if you want to borrow my OBD2 scanner (a D900 with real-time data display mode) then PM me so we can exchange mobile numbers and agree when to meet in the car park there.
