1NZ-FE high cold start

[Jebus]

I have a Fielder with a 1NZ engine, on every cold start the revs jump up above 2000rpm, usually between 2100-2200rpm.

This sounds odd and I cant imagine is good for a bone cold motor. Is this normal? or is there something I should be adjusting or replacing?

Thanks,

Nope, mine is only just over 1000rpm when cold, settling to 600-700rpm when warm. I had a similar problem recently where it would shoot up to just over 2000rpm when cold.. turned out that I'd accidentally turned the AC on without realizing. Lol..

Ah thought so, how would one go about fixing this?
