Toyota Carina 2.0 - Toyota Carina e 2.0 over reving during idling - Gregory II

I have a carina that on idle is idling too high at 1200-2000 rpm. I tried cleaning out the throttle body with no joy. What could be causing this, i.e. which sensors can be tested for this? Has anyone come accross something like this before,

Thanks

Greg

Any ideas? I have tried cleaning the idle control valve but to no avail.

I have located the idle control valve. The manual says to check that this functions mechanically: can these be cleaned at all?

I have heard that the hole that is found just before the butterfly leads to the idle control valve. Is it advisable to spray some electrical contact cleaner here, or will this have no effect on the idle control valve?

Thanks again.

Hi

I have checked the temperature switches/ sensors. Can the idle control valve be tested at all/ cleaned out? Also, out of interest with what are starter motors cleaned with?
