My Logan accelerates too much

Hello Friends of the Forum, my Renault Logan accelerates and reaches up to 30000 rpm, when I turn on the a/a it goes to minimal and almost turned off, I changed spark plugs, spark plug wires, gas and air filter, injector cleaning, IAC valve (generic) the original is not achieved, it was scanned and according to the technic Damaged and does not send signal to the IAC and TPS, after all this it still accelerates now it has dropped until the 20,000 rpm and continues almost until it goes out when I turn on the A/A, greetings and thanks in advance from here from Venezuela

The majority are changing pieces. Trust of a friend your self but your problem is air entrance or a bad emptiness hose that this game
