Idle Issue
My car is fitted with a Sierra 2.0 8V DOHC with the stock engine management and injection.
Recently when starting from cold the idle has been going to around 1800rpm before dropping back down - if you then blip the throttle, the idle sticks
again before dropping.
This carries on until the engine is warm and the ignition has been swiched off once - it then idles perfectly as it always did.
If you disconnect the ISCV wire when its doing the high rev thing it idles at normal idle even when cold.
I think the ISCV is working ok but something is telling it to hold the revs high - any ideas what is what ?
I think it started doing it after fitting a new alterantor belt but cant be sure exactly when it started.
Thanks

Check the TPS is working correctly.

Take the Idle control valve off and give it a good clean out with carb cleaner or similar.
Phoned the local ramblers club today, but the bloke who answered just
went on and on.

As above, I'd should stall dead with out it connected.
