Mr. CharlesY, I dont want to intrude,
So, IMO plugging in a tester will at least reduce the diagnose area.
My advice for everybody with strange missfire which is not pump, filter or oil ingress related is to plug in tester ASAP cos i saw two times in the last 2 years(i admit this is not very common) this kind of missfire generated by a bad earth to ECM which ended up with ruined ECM.... there is an earth rail near the ECU with 3 points, always check the middle one to be perfect !!!
You can intrude all you like because your intrusions are sensible and helpful!
Can you ship a pic of the earth rail you mention?
Where exactly is this troublesome connection?
My TD5 Disco turned 93K miles today, so I will be happy to check an earth point tomorrow!
thats why doing one thing at time helps to prove what was definate fault ,although some faults can be a collection of small faults in a a lot of parts ,getting your own hawkeye or similar is a good idea ,even if it doesnt show your fault either by fault code or live data at least youve ruled out a lot of potential faults ,but pleased it seems betterOk what can I say, mixed emotions...
Fitted the new injector harness and head cover gasket.
Cleaned the MAP (?) sensor in the intake manifold that was completely caked in oily crud!!
Changed the fuel filter... I had no idea it got so very HOT...:suspicious:
New air filter .. and successfully broke of the plastic tabs of the air filter box :censored:
And it now appears to work... took it for a drive no issues... yet..
Whilst I am prepared to accept it was the loom ... there is a part of me that just can't remove the niggle in the back of my head that says something is still a miss.
Still want to get it plugged in and have all the faults cleared and then checked again...
So thank you ALL for the help, suggestions and support

It is interesting to note that all this trouble took place, and NONE of diagnostic tools would have diagnosed it. They would have said there was no fault.
since you seem so bitter ,its also interesting to note that injector loom you thought so insignificant needed changing, and diagnostic kit is extremely useful with td5Changed the fuel filter... I had no idea it got so very HOT..
In normal running, the fuel filter of all TD5s will get far too hot to hold on to.
The fuel gets VERY hot in the TD5 Injectors, so hot that it would not be safe to let it go back to the tank. So the fuel spilled from the injectors is mixed with the main flow passing through the gallery in the cylinder head. Then the very hot fuel coming back out of the cylinder head passes though a FUEL COOLER that uses the radiator return coolant to drop the fuel temperature to about 70°C, which is hot enough to cook meat.
This hot fuel is sent back to the fuel filter, and then it finds its way back into the fuel tank.

I assume this is your parting shot at jamesmartin ?.
Get your head out your arse you prick !!.

Once again I ask, IN THIS CASE, in what way did any diagnostic tool assist in the resolution of the problem?
Your choice of language reveals your nature well.
If you insist.Pathetic !
You,ll have to do better than that to, " wind me in ", maybe an attack on my grammer and spelling ?.
