It is revolutionized alone

Hello friends, as you will be new in the forum. Thanks to you I have achieved several Kia manuals. But there is not that of the Carnival Kia 2500 V6 150CV of gasoline, which is what I have. My consultation and problem is that I get around up to 4000 rpm alone when you start and be in the dead man. When you are going notes that are revolutionized. Please you could help me to solve the problem. Thanks and greetings in advance.

Czech false air tickets, in the hoses of the acceleration or admission body, check the proper functioning of the IAC valve, and finally Czech the tenneur sensor, the electros are always working? or do you have thermventilator?

Thank you kikemec for answering so soon. Sorry to bother you, but I could tell me where all the elements that you tell me are located, to be able to check them well, because with so many hoses and valves I go crazy. Help me.
Pd. I hope not to bother you and be heavy.

Fercom, seeing your answer I relate it to knowledge, take it to a workshop and indicates to review

It is not annoying to help photos I can not send you because I do not have, even if I will be taken to take pictures of the vehicles that I repair to help them better, the hoses are the ones that reach a round mouth where a large hose enters, the IAC goes to the side of the body where there is a pariposa inside (butterfly = golden metal disc in the body where the large hose enters From the thermostat where the hose that enters the upper part of the radiator is born, or somewhere in the cylinder head, electrventilator is the fan of the radiator that works by current, the thermos fan is the radiator fan that works by thermal gel and is in the engine and floating in front of the radiator.
