1997 rav4 auto noticed today when I started the car up the rpm was fine normal under 1,000 the normal, but when I went out of park it shot to about 1500-1650ish Rpm close to the 2I mark, stayed there when I put it in park. Turned off the car then back on shifted it and the rpms were normal again. This same also happened when I got out of work. Also when the car is warmed up or I restart the car it's fine. And the engine is quiet, the trans goes into gear and shifts fine, this is only on cold first starts is there an issue or is it normal and Im just being paranoid?
