The throttle cable will have nothing to do with idle speed or quality . Actual idle speed controlled by the ECU using data received from various sensors. The ECU drives the iacv to achieve the correct speed. The iacv can clog up with muck. It's easy to clean with a couple of squirts of carb cleaner or even some Wd40. There should be about 5 mm free play at the throttle pedal.

Let us know when you find it - what is it?
Does it need any attention?

Mines not see a technician for servicing for at least 5 years and I've never looked at this - will have a look at the weekend!

No need,just make sure the ignition is off.
All you need to do to clean the iacv is pull the large rubber pipe off the Throttle Body (TB). Start the engine and spray some carb cleaner or Wd40 into the pipe while it's idling. Rev the engine a couple of times as this actuates the iacv. Repete this a few times and you are sorted!!

Far better to remove from the car and clean it - you dont really want the engine eating all the gungy sh*te they collect in them.
Thanks, will take a look - tbh my tickover is fine but I dont want "gungy sh*te" anywhere

Well, peered at it for a bit. wriggled the pipe to check that was OK, then reverted to aint broke, so don't fix and shut the bonnet. It is located on the front of the throttle body - as per pic earlier in this thread. tbh I'm not sure what it does?
I'd not pull it apart to clean it if it's working as there is an element of risk to it's integrity if you have never pulled one apart before. It ain't broke so don't fix is a good one to follow.This is why I said use cab cleaner. The gunge in the valve is only what the engine spits out the breather to be burnt anyway. As for what it does? It's basically a motor driven valve that allows an amount of air to bypass the throttle butterfly. This means the throttle butterfly can remain closed on things like over run which helps engine braking and emissions. The ECU is able to control idle speed vary accurately and quickly using a combination of iacv position and ignition advance.
I hope that explains it's function?
