Acceleration and restlessness of a Renault Twingo

Good night friends of the forum. I have a 2005 Renault Twingo and for some time it has been presenting an acceleration and deceleration failure which is removed and returns to the days the acceleration body changed spark plug wires and spark plugs and continues to present the fault takes it to the consequence and tell me that it is the computer. Who can help me have the experience in a similar case. I don't want to keep spending money in vain. Thanks for the help

The same thing happens to Mazda and it was the computer, you can do it is to disconnect the Vateria the negative, wait about 3 minutes, and then you connect it, then before giving Arranke you open and close the contact about 4 times at intervals of 20 seconds and then you give the Arranke to see Ke pass.

Sorry already checked that the hoses are in good condition and that there are no false air inlets.

Thanks friend I'm going to take your advice into account and then notice how I finish going

Hey Roniel, how are you? Could you solve your Twingo's problem? I have a Twingo and it is presenting me that same fault, I did cleaners, I bought a new IAC valve and nothing remains the same, the only thing is that before maintenance the air conditioning was turned on and off (compressor) very often since the car imagined the minimum did not endure it, I had to accelerate it to activate the compressor. Now it has everything changed, maintenance done but still with the fault? Greetings
