Hi I've never contributed here before but I do read the forum quite a bit so hope it doesn't seem cheeky that this is my first contribution.
I recently bought an astra 1.4 16v and have noticed that when it is first started it revs up to around 1500 - 2000rpm. However after just a few minutes driving it settles down and idles perfectly normally. The problem only seems to re-occur when the car has be switched off for a fair few hours such as when I come to start the car again after finishing work.
The car seems to run perfectly fine other than this and fuel economy and performance seem just as I would expect.
Hope you can shed any light as its quite annoying!
