My daughter has a 2005 Focus petrol auto. On start up the revs shoot up to about 2000 rpm for 3 or 4 seconds, before it drops back down to a normal idle. No fault codes showing up.
Any idea what it might be causing this? Drives fine all other times. I'm assuming it would have an electronic throttle body? |
