It's an automatic idle, the motor needs to run at a higher RPM for a few moments to lubricate the valves and pistons, perfectly normal operation.

Check the engine for proper cylinder compression. If the pressure is low then a blown head gasket could be leaking and causing the problem.
When you start a car and has high rpm is that bad?
It is not good to rev any engine immediately after starting it. The lubrication system has not fully charged and oil has not reached all the parts immediately after startup. The oil is also thick and is not flowing as it will when the engine reaches full operating temperatures. So, the answer is Yes, that is a bad thing.
How does a lightweight flywheel improve car performance?
A lightweight flywheel doesn't make the car go faster because it doesn't increase the power output and the weight that it saves is irrelevant. What it does is that it improves throttle response which means that it makes the engine rev quicker, and it makes the car feel faster.

What is the purpose of a computer in a car?
Part of the purpose is to allow the car to change how much of a choke there is when you start your car. So that you get the best possible start when you start your car. It also allows you to select how much of a governer is on your car. The governer ditermines how fast you car go before it cuts off the gas to yaour engine. When it reaches that limit your car will slow down to a certin speed then the engine will kick back in and you will continue on your journey. The computer will also allow you to detirmine how high of a rev limiter that you have. The rev limiter allows your car to reach a certin rpm(revolutions per minute) if it goes any higher of a rev limit then the engine will explode. These are the only things that i know of. If you want more information ask a professional mechanic.
