I have a 2012 Levin SX Auto ZRE182R On COLD start up, after being garaged over night, it will rev to 2000 to 2150 RPM on start up before settling on about 1500 RPM. It will do this 50% of the time on cold start up, otherwise it starts up at 1500 RPM. I Have taken it to two different Toyota dealerships, and both have told me this is normal. My argument with them is, that if it was normal, it would consistently cold start at either 2000 RPM or 1500 RPM, and not 50% of the time. Has anyone else here on this forum experienced this odd cold start behavior.
