What is the correct idle rpm cold for a 2001 Camry 4 cyl. The following details may be appropriate. Ambient temperature 52 degrees F. Immediately upon starting rpm goes to approximately 1700 rpm in about 5 minutes it will settle at 800. Is this normal?
For 52 degrees that sounds a little high for much more then a minute. I would check the cooant temp sensor. In really cold weather it might be a little closer to normal. My 04 will start up high but will start dropping after 30 seconds or so.
