My car sound horrible on first start, the revs hang up to about 2k on the first start but I can turn it off and start it again almost immediately and it starts like normal.
Any ideas why?? It's doing my head in. It doesn't always do it on first start but 8/10 times.
This is first start

This is second start after driving just up the road for about 10 seconds
