4.5 throttle linkage wear and general poor running
Discussion
You may get another - it refuses to start now.
I wasted a load of fuel in one of my proper cars trying to jump it when it ran out of electricity cranking, and it's now recharging for the night.
There appears to be nothing amiss on RS-AJP and I double checked the HT leads were plugged in to the correct cylinders, the correct plugs on the coil packs and that the coil packs were plugged in to the correct loom for their respective banks.
I hate this car.

You're dead right 
I've just driven it though. It's freezing cold, wet and trying to snow but am happy to report that I've had WOT in 4th and 5th with no misfiring or juddering. That's great.
It's now idling a bit fast at around 1250rpm according to the tachometer so I'll need to look in to that, and whilst down there I need to see if I've dislodged a plug slightly from the starter motor.

I haven't renewed the insurance so took it out yesterday on the last day of cover before putting it away - and after slowing down on overrun, turning on to my driveway and applying a bit of welly at low RPM in 1st, it bogged, slobbered and stuttered again. The HT leads made a big improvement to the drive but apparently they weren't the underlying issue.
I'll sort the starter motor solenoid in the mean time, then ask Joolz nicely if he'll take a look in the new tax year.

So the car got a new fuel hose on Friday and did a good 80 miles or so running absolutely fantastic.
I used it in traffic yesterday and when fully warmed up I declutched to come to a halt and it conked out. It refused to start again so I called American Airlines (apparently The AA is not the first hit when you Google "AA"). They couldn't help but two guys gave me a push off the road whereupon it fired up again. I used it again today and it cut out half a dozen times or so but I bump started it using the car's momentum and the clutch.
It idles fine, maybe a touch low at 900rpm, but only cuts from over run. If you bring it down to idle with throttle it's fine. You can tell when it's going to do it because it stops popping and banging and just sounds like a generic crossplane V8 slowing down - then you declutch and it just stops.
It dawned on me on the way home, managing downshifts, revs and throttle very carefully that I didn't 'plug' the pressure sensor hose back into the n/s airbox after doing the fuel hose so it's measuring engine bay ambience.
What does the ownership reckon? I'm going to sort that obviously and tweak the idle a smidge higher. Do we think I have another new and elaborate issue, or have I just been a t
t leaving that hose dangling by mistake?

It's done a around 400 hundred miles over the past fortnight so even though it got lightly rained on whilst parked outside one day, it has been fully heated up and I don't think it's likely to be damp - particularly as it has only manifested itself when hot.
The first day it refused to start again until it had sat for a few minutes - the second day I bump started it again using the clutch and momentum
I haven't had a chance to look at it yet but my pickup is getting a new windscreen tomorrow at home (2,500 miles and 9 weeks old - good going to smash a screen already!) so will sort it then. I need to replace the screenwash tubing too. It's been spliced together in several places past the engine and it keeps falling apart so time for new tube!

Or Lambda's.
Or damp from being stood.
Lambda 2 Or damp from being stood.
It ran like a bag of nails on the way home today at low throttle. Push the pedal and it sorted itself out.
I plugged it in and both AFRs are lit up red and Adaptive 2 is on the limit. I cleared the adaptives and it instantly idled properly, until driving it up the driveway plugged in and Lambda 2 lights up red.
I'm pleased actually. It's a relatively cheap fix and it hasn't led me round a wild goose chase!
Lambda 2 has logged a fault again. This time it's stuck at just under 2 volts. Has anyone seen a failure before? I'm not quite sure what it means. It runs badly with high adaptive differences at light throttle, idles low but clears up and takes off at wider throttle openings. I don't think it's a genuine overfuel.
My understanding is that the lambdas are ignored above 50% throttle too, and mine is fine at high revs and with wide throttle positions. It's just light to mid range as of today. Lambda 2 is stuck at the highest voltage with fault code logged. Drive it for a bit and the adaptives diverge until I get AFR2 fault as well.
One of the new lambdas fell apart from the box. The steel cap covering the element is tack welded on, or is supposed to be. It broke off one of the 2 new ones as I pulled the plastic protection cap off. The other one seemed fine but I'm wondering if that's fallen to bits in situ and the element is just burning away in the exhaust stream. Either way, the chassis brace and exhausts need to come off again.

Much to my shame I've neither fixed nor driven the Cerbera since my last post. I managed to lose last summer due to the car being worked on so rather than do it again I need to actually do something.
Since the last sensor porked itself after a month or two, I decided to buy a cheap universal fit sensor.
It's a 3 wire (black, white and red) NGK NTK Titania sensor and I found one on eBay for £17 plus a tenner postage from the USA. Much better than £90 for exactly the same thing but with a Rover plug attched at the other end of the wires.
