1.1 Active Eco
I think standard driving practice on a 1.1 on hills, is to rev it 'til your teeth vibrate.

Hahaha - that got me! If it's not about to fall apart like Peter Perfect's car, you're not doing it right.
There is definitely something up though. What that is, though, I'm unsure. Or I'm simply asking too much of the poor thing.
How many miles ago were the plugs last changed ?
OP
OP
Not many, I want to say around 2k ago. New plugs, new coils, it was mostly fine for a few months, and since maybe 5 months ago it's been on and off like this. I kind of accepted it as I wasn't on many long journeys, so it was mostly unnoticed at 30mph city driving.
Does it idle smoothly or can you feel a bit of vibration
Do the revs ever fluctuate at idle
Is there and difference between hot or cold engine
Plugs should be good for at least 20,000 miles
These engines run remarkably will on three cylinder
Here's mine on 4, 3 and 2, your coil pack is slightly different
Notice on 3 how little difference there is you can just see it if you look at the cam cover edge but it's fairly obvious from the exhaust exit
We need to know if it down on power due to one cylinder not firing
If you have a scan tool and look at the fuel trims
They would be way positive if there was a misfire

A bit of vibration. I'll pop a video below (it wasn't doing it as badly), but it has a kind of judder a bit when it's in idle, as if gasping for air.
It doesn't appear to be revving, and if it is, it's slight.
Good question, I think it's better for the first say 45 minutes of running it than it is into a 3 hour journey. I'm perhaps just thinking that, but it definitely was struggling yesterday when I got further into my journey and was motorway driving.
Thanks for the video! That at least gives me something to test. I was going to remove the ECU too and spray some contact cleaner on as well to check if that was causing any issue. It does look like it has been cable tied in the past.
P.S. Forgive the mess of the engine. Next job, now that it's nicer weather, is to give it a good clean inside. I got a lot of the muck off the bottom of the car recently. I was amazed how much of it looked decent nick with just a bit of TLC.
EDIT: Just copied what you did in the video. Unplugged one of the leads. The first lead (closest to the front of the car) made it judder slightly more. When removing the second lead, the car was barely functioning.
I also unplugged the ECU to see if there were any issues. It could be a red herring, but the smaller part of the module seemed to be causing an issue.

Put your hand over the exhaust pipe
Does any pressure build up
Sounds like there's a hole in the exhaust but different phone recordings sound different
Post a few seconds from the back of the car
Don't put the phone too close maybe an arms width away, otherwise it pick up the gas stream
I am trying to listen for a regular pop sound, but it is harder to pick up on a phone than in real life
I can't really describe a sound but It should go something like
pr pr pr pr pr pr pr pr pr pr pr pr a constant purring sound
But if it's misfiring it goes
pr pr tu pr pr tu pr pr tu pr pr tu
Regularly purring is interrupt by a sort cross between a tut and pop sound

Here's a little video from the back. It is making some amount of noise. The last time I was at the garage they mentioned it, though they didn't say there was a hole in the exhaust. I'm sure they had mentioned something else, something to do with the water sitting in it, from memory.
Cool thanks for the video
Sound like a hole and a misfire, but it's hard from a video, especially as the exhaust is noisy
Put you hand over the the end, to block it off, you need a helper to do this really
Listen for leaks in the manifold down to the flex joint
Any past here do not effect the running at all
But if it pre O2;sensor at the top of the engine the running may be off
Take each spark plug lead of the coil pack one at a time, start the engine and see if one makes no difference
If they all make a difference it's no a misfire in on cylinder causing the lack of power
If one makes no difference, that one is not contributing much to the engine at idle

Before I've done the rest, I can tell you one of the leads made the car judder a helluva lot! Could it be as simple as, despite being new, one of the plugs or leads has simply given up?
I guess it's shaking like in the video I posted earlier when it's running on two cylinders
Go through the test one at a time
We need to know if
1,2
3,4
1,4
2,3
If it's not firing on 1,4 or 2,3 it's likely to be a coil or it's wiring

I’m hoping this works as uploading from a phone. Forgive the probably horribly unsafe video, the leads seemed to rumble out of place, catch metal and spark a bit.
First video is running on 3,4: Rumbling, but works
Second video on 1, 2: Rumbling, but works
Third video on 2, 3: Won’t start
Fourth video on 1, 4: Won’t start, but seems like more life.
Fifth video with all plugged in for good luck

Both coils are fine,
Good chance all the plugs are fine
Good chance all the injectors are fine
The head gasket hasn't gone between 1,2
Everything is as it should be
You appear to be running on all 4 cylinder at idle
Test the exhaust as per previous
Take the MAP sensor out and look if it's covered in a white oil emulsion
It's on the side of the black air intake, held in by one torx, you can leave the electrical wire connected normally
Good suggestion koalar. About a year, possibly slightly longer, after Becky joined the "family fleet" and after I'd done all the outstanding stuff I considered important - new cam belt kit, full service, new front shockers and top mounts and a few other things I decided to clean her Map sensor. She was, I thought, running quite well before although I did feel that she "held back" a bit on large throttle openings. The sensor is very easy to remove, just one screw holds it in, and when I pulled it out the end was absolutely drenched in engine oil, but no Mayo. I cleaned it with sensor cleaner - brake cleaner works just as well I'm told - and the difference was quite noticeable. She was considerably more "eager" and pulled more strongly. I now clean the sensor every year as part of the service procedure.

Just checking, are we talking about this here?
And it’s dawning on me how useful it is having a driveway like I have right now - haha!

That's the one

So, as Jock mentioned, drenched in oil. Should I be wiping it down completely? Only thing I’ve got available is WD40 connector cleaner.
No, not wd40 it will leave a wax deposit
.
Brake cleaner
Carb cleaner
Meths
Hold it downwards and flood it
The circuit board end isn't sealed I believe
Just to get it working you can probably get away with soaking it up with some toilet tissue
Poke a rag down the hole is the manifold full of oil?
