Both my German manuals say 2000rpm, maybe there is a difference between Euro and US.

What you say in step 11 only applies to cars with airco, as I wrote earlier. Without airco set the gap to 1mm. And of course test with car in drive, power steering at maximum and airco on.

Never put car in drive if you are not sitting in it and/or there is someone in front of the car. You would not be the first to be surprised by a car taking off while adjusting the idle. The parking brake is not that strong.
