High Revs When Engine Cold

[thatfatbloke]

When she fires up after being stood for a few hours,the revs seem rather high to me at around 1400 rpm. After around a mile she settles down to around 700 rpm. Is 1400 too fast for a cold idle?. If so what is the most likely cause please?. Ta.

Thanks Matthew. I just don't remember my old LS revving that high when cold. Mind you,that was three years ago,I've slept since then!.

Not sure mine revs that high, more like 1000rpm I think, but I'll try and remember to check tomorrow morning.

Haha your all getting old then,it's normal guys,my IS200 starts off at about 1500 rpm when cold and then gradually drops to about 650 rpm happy days.

I'm not getting old, I AM old, but I was right about mine.

Just been out, on a fairly chilly night, and it idled at 1000 rpm exactly.

Bottom line is the colder it is the higher they rev,and after a few minutes drop to normal
