Is that normal?

My name is Christine and I bought a Kia Rio year 11/2004 in November 2013. The car has now run almost 70,000 km, got a large inspection when buying and the timing belt has been changed. From the inside and outside it looks like from the sales room of the Kia dealer. Whether this, however, employs besides good sellers also qualified mechanics, I dare doubt. Because somehow w my problem with the Rio always with the words `That’s normal, don’t worry. I am blonde, but soooo blond now also not! Here’s my problem: As soon as I step up the clutch the speed increases by 200 to 300 revolutions. If the engine is cold it can also be 500 revolutions. My father says, `the engine gives intermediate gas`. I don’t know what that is? But must probably be a relic from the beginnings of the automotive industry. It is unusual for me that I can drive with the Rio without giving any gas. I just have to kick the clutch, insert the gear, let the clutch come back, and it starts without having to step on the accelerator pedal once. In the fifth gear it purrs through the area at 45 km/h and can’t be impressed even by slight climbs. The speed remains constant at approx. 1100 revolutions. If I then switch to idle and the car still rolls, stay t the speed also at approx. 1100. Only when I stop and the car stands the speed decreases to approx. 700 revolutions. Is this really normal?
