As Tosh has been posting, we're doing quite a bit of work to his car.
Whilst she's been in the workshop for such a long time I've begun to notice that she doesn't cold start as well as she might.
A quick check with the test light revealed no power to the supplementary injector whilst cranking and further investigation revealed a failed thermo-time switch.
With power now restored she starts up willingly from cold but the cold idle isn't good so I took a look at the auxilliary air filter and found it to be partially blocked.
I thought it would be a good idea to take a video of this as it's really such an easy test and these little filters are so often overlooked. Very few of the many cars I see have had new ones fitted recently.
With a COLD engine, loosen off the air filter so that it's just in by a couple of threads. Start the engine and then remove the air filter whilst the engine is running. There should be a significant noise of suction from the orifice now exposed but there should be NO increase in the idle speed. If the idle speed does indeed increase then you hace a blocked auxilliary air filter and it should be changed. A final test is to install the new filter whilst the COLD engine is running and you should observe a significant drop in noise but NO significant drop in idle speed.
Here's a link to the video that illustrates this:

Whilst I was at it I thought I'd check the throttle switch for function and it turns out that that isn't working either but that's another story........

Stick, Tosh--
Great little video. Someone should add the part number and if the part (air filter) is still available?
Has anyone considered creating a dedicated youtube "channel" just for videos created by members here? I don't know too much about it or how to do it, but some of my friends in other walks of life have dedicated channels on youtube. Might be a nice way of organizing them.

Two different part numbers according to your model:
000 075 11 32 for 250/280 or 000 075 06 32 for 230
