Hi, I bought a well-worn 1994 Land Cruiser four days ago and I don't have a factory manual yet, so pardon the basic questions. What is a normal fast-idle RPM, starting up cold, on a moderately cold day? Say, 40°F. How quickly does it drop to the (I think) 650 RPM regular idle? And does it normally stay spot-on at 650 RPM with the vehicle stopped and the transmission in Drive? I've currently got a surprisingly high cold-start idle, like 1600 RPM, and it's sometimes bogging down a bit when I come to a stop.
