high idle when warm.

[mr_K]

Im having problems with my glanzas idle.

when i first start it from cold it idles around 1400rpm and once it warms up the idle stays on 1100rpm.

what can be the cause? Ive checked for air leaks and cannot find a leak.

Anybody know?

Thanks

Sounds like the idle up valve on the end of the inlet is playing up. As the idle drops when warm so that would suggest the wax stat in the throttle body is working.

Unplug it there useless and tick so loud

Ill unplug it and see what happens.

its also forged can that be a cause for it?

If your idle control valve is broken, you will get a stable high idle between 1000-1200, because the valve is leaking all the time. Unplugging the connector won't help as the copper thing keeps it shut and solenoid opens it when needed.

Where can i get a replacement idle control valve?

I need this sorted because the petrol consumption is bad.

thanks

From Toyota, the price is around 200euros or take a risk and buy a (broken) secondhand one

[mr_K]

Lol..

im going to try get hold of a used one and hope that its not faulty.

Cant i run my car without one?

Take it off and block the hole on the intake mani?

ICV valve on ebay

You can take it off and block the hole, but it might be a bit jerky sometimes on low revs thou. At least mine was when I blocked the valve from inside.
