I personally don't know what the specified engine RPM is supposed to be when it's cold. I don't use the coldstart device. I don't idle my cars, it warms up faster when you just drive it gently. One time when I was moving I let the car run for almost a half hour and I still didn't have any heat and the engine temperature was still buried in the cold. If I just take it out and keep the Revs low I have heat in about five minutes.
