Seat Ibisa 2002 Failure

Who helps me with a Seat Ibisa failure loses the acceleration and change gasoline pump, coil, spark plugs and filters, sometimes fails when it is heated, in cold occasions I will thank you for your help

I had a very even or equal problem with a Fiat Punto, it changes the same as you and I was the same I was more than three months with the vehicle and the problem was the oxygen sensor, do not ask me why, that I know that this fault would not give it to give that sensor and more explanation I do not have it changes it and everything was not good, I had not checked or anything, it only occurred to me in despair.

M you could help where I locate the electrical diagrams of Ibisa's control I also think that it is the oxygen sensor but I want to know which of the 2nd the front or the back, they already scanned it to me and if the oxygen sensor comes out but which, I thank you very much your comment to have in my friend your server and in what I can help you count on it. Thank you
