    Is it normal for the engine to turn on for about a minute when you first start it? Mine always does it, seems normal, but just wanted to check and also find out why. I assume it has to power a couple electrical things in the car?

    engine runs to warmup temp to meet emmisions and be ready for power requirements. it takes a minute now, but will take longer as it gets colder.
