High revs when starting X reg Corsa SXI - holly1
Advice needed please. In the past few days I have noticed that when starting my X reg Corsa SXI 1.2 16v from cold the revs seem much higher than before.

Until this week when starting from cold the revs would increase to approx. 2000 rpm and then drop to 900 - 1000 within a few seconds. However, this past week the revs have increased up to 3000 rpm, although they do drop down to 1000 - 1100 within a few seconds. Any ideas what could be causing this and if it is a major problem? Would prefer to get it sorted before it becomes a big problem. I've not noticed it being exceptionally cold the past few days although there have been one or two days of icy windows.
