Luz Check Engine

Hello, my old man looks at being together, it is best to see again what the diagnosis says, since in the long run you would avoid a lot of money in incorrect spare parts, it may be that you have a problem of spark plugs, of coil crab, injectors, etc., I would have to see it but I am here in Chile, check the fuel and air filter, it is all that you can do without tools.

Pos yesterday I did the diagnosis with a friend and it appears to me that it is the oxygen sensor (the one in the manull) and also leaves a high dead point as I explain my friend is a sensor that indicates the post -row of the Sigual if it is above or abaja to see Siel Pistob rises and low ..
ntances today bought the oxygen sensor and the other I have to verify if it is well or if it is well or if it is well or if it is well or if it is well or if it is disconnected.
And I hope that the damn light will go out and stop failing ,,,
the sensor fails since I cleaned it with WD40 that day the car to fail hehehehehehe

What sensor did you clean with Wd 40?, the oxygen?, the other sensor that you say I think they call it a detonation sensor, which is the most that resembles what I know, now the detonation sensor uvica in the cylinder block almost when it reached the añure of the cylinder head,

No old and fixed the sensor problem I already put it new and my car is excellent, now I only lack the other sensor that C calls a high dead point, but not C where it is located, I already downloaded the manual of my car on this page but I can not open it I get out that the file is damaged
, they can help me with that manauel (Hyundai elantra from 96 to 01 (English))

Thank you beforehand beforehand

You already bought that sensor too, it will be easier, that you ask the guy who sells it to you and you do not need manual or anything like that, it is my umilde opinion.
