In Ciudad it is perfectly well, several people have told me that it can be a problem with the oxygen sensor but nobody has given me the security of K outside that exactly, I hope they help me with me problem thanks.

The most ideal is to shine it to see if you have any code taxed in your memory, since several sensors can cause you an intermittent failure.

It is true the most economical solution is to scan it and then see that sensor is therefore this failure can be from the TP of the temperature sensor, oxygen evaporation of gases and a lot more, scan it and comment.
