Chevrolet Corsa (Opel) failure

Good friends, I would like a little help, my corsa began with a fault that seemed spark plug That it was the IAC, I change it because that if I checked and is bad, but now it has spark plugs, spark plug wires, IAC, oxygen valve and even new distributor and still with the clear failure is now very minimal, I stop smoking the spark plugs but still with the fault. Can they help me? THANK YOU

Good night friend review first the Bacio del Map hose and verify if there is a bacio then check the gasoline regulator and verify if there is bacio if there is bacio in both the MAP is bad that is the only sensor that produces that fault and the smokes

Thank you friend for your answer, and sorry for my ignorance, but you could describe what the MAP is.

Thank you, what is the MAP sensor, disconnect the hose and the car goes out. that of the gasoline regulator does not make any type of emptiness.

In the regulator there is no empty handle if I do not have it to take it out and check that it is not stuck and if she has it she has to make empty during the acceleration and the MAP goes out it is because the sensor does not do the proper work tries to locate who has a unoy tries it because she would keep her on but with a failure would not be left out. The car or not also check the temperature valve that she also sends a very low signal to the ECU and she sends MAP and the pump that sends gasoline because it is very cold
