Hello good thanks for the answer, but I would give me some electrical failure and which does not give it to me but in case I review it, where it says that it takes it at the entrance and at the exit of the catalyst you can not send me a photo or similar lake for you to guide me, thanks and greetings.
You normally as you walk with the car, if you go slowly or in the city before changing something you see on a highway and give a good pull in the car and keep it for a long time in high revolution so you can clean the probes that it carries a little, then check the spark plugs and put the originals if they are spent that they do not cost so much and those intacts are not repaired because they are sealed then you see the probes.
