For what you say that problem is the accelerator sensor that goes sensor goes on the accelerator pedal only you have to change it and the other does not buy it used only new

Hello: if the vehicle has more than 100,000 kl. It is possible that the Catalitian is poor and obstructs the exit of the gases normally causing excess temperature in the Lambda sensor, uncontrolling the slowdown with acceleration oscillations.
It must be remembered that the Lambda sensor cannot be exceeded from 400 to 450 degrees ℃ If this passes the sensor is damaged and the "olfatus" will be deficient causing the electrical signal coming from the computer to the IAC valve to be in intervals sequences causing the oscillation and uncontrol of El Readi.
