pipe identification please
Discussion
Can anyone give me then name of this hose please? It was the one in a previous thread that Britishtvr450 told me to blank off to set the base idle tgats fed under the throttle cable linkage, I noticed some insulation tape at the other end hidden behind the throttle cable linkage, a bit of a giveaway I think, maybe that's why I was having trouble setting my base idle

see, when you know what it's called its easy innit!! thank you, while you are there, Ive also tried to find the spark plug extenders/adaptors as they seem to be called, I've searched for both and only come up with ACT again, but out of stock, I did find an old thread on here that suggested they were a Vauxhall part and only a couple of quid, is that right? Thank you very much, i did search but didn't know what is was called so that's why i struggledEdited by Andy70 on Sunday 4th August 17:15

Yep, I have a full set of working extenders in my loft for exactly the reasons Blaze points out.
Now using leads with angled boots and decent heat socks.
I think my extenders are ok, I hope they last then, I just wanted to change them for piece of mind. Now using leads with angled boots and decent heat socks.
The car is running much better now, until i order a new hose I at least had the foresight to glue an innertube puncture repair patch on before i wrapped it in insulation tape, it seems to have done the job, the car is still lumpy a bit on tick over but revs are settling better now, when I changed the sparkplugs they were really sooty, but its more manageable to drive, I'm actually enjoying it

Try too as soon as you can Andy.
He will identify if you have vacumn leaks and any other possible faults leading to rough idle.
so how does the rover gauge work, does it log info as you drive? the thing is, issue are intermittent, so in other words it has to be running crap to identify problems?, I'm learning as I'm going, it seems to be getting worse, as the car is warming up it drives lovely, i turn engine off then on again, and it wont tick over.... sometimes, hence why I was struggling with the base idle, the next morning everything was all good, I've looked at threads regarding the coolant temp sensor, but cant seem to find it, for 10 quid, i'd change it, then i saw these plugs not connected to anything (in a separate post) I can only presume the issue is related to something that's failing when getting warm, I like to replace the ht lead extenders, but seemingly difficult to get hold of, I assume HT leads are ok as the car has done 62k and it has Magnecor leads fitted at some point in the cars lifeHe will identify if you have vacumn leaks and any other possible faults leading to rough idle.

Air flow meters are the main culprit for playing up especially when heat soaked.
Check the connector and the terminals look ok, remove it and inspect for cleanliness.
Id wait it out for the stepper hose as i dont think thats the source of your problem, the Rovergauge log will help i think you will just run the engine without driving for the log file but Blaze will confirm.

As Belle427 says......the logfile file can be created a number of ways. Ideal is to start logging data from cold to hot whilst driving followed by 5 full minutes of static idling. This way I can assess all the ECU inputs and outputs for full range operation and idling performance. If you can't achieve that because the car just won't do that then a logfile with some idling will have to do. Because your situation appears chronic it may well be easy to spot. I will post exact logging process here in a bit.Check the connector and the terminals look ok, remove it and inspect for cleanliness.

OP sent the files and all the ECU inputs and outputs look good EXCEPT the Idle Control Valve (ICV) and TARGET IDLE
The target Idle has been recorded by RG as 0 (zero) either very odd or not check boxed to be recorded.
The ICV on most well running cars is in range of 20 to 40 % OP's is running at 1.5%
This suggest either something really odd with the ECU not have a target idle or more likely a bad base idle being set or vacuum leak as yet undetected which is preventing that from being properly set.
If we can establish the target idle exists and it simply wasn't recorded then suggest a smoke test to find the vacuum leak. If there really is no ECU base idle then maybe fit a known good ECU (I have a couple of spares if needed)
Here is what ICV control looks like OP v mine.
