Over the last week my 2006 Astra 1.6SXi has developed the following problem. This only seems to happen on the first start of the day, for the rest of the day no matter how many times the engine is turned on it seems fine.
When I start the car of of a morning, the starter sounds healthy, turns the engine, the engine starts but almost at a reduced idle which sounds clattery and shudders a bit. If I then press the throttle it seems to fire into life and is fine!
If anyone else has experienced this I would be interested to hear their thoughts!
