Problems starting and spending changes

In the Hyundai Elantra 1995, when accelerating loses strength and sucks, then when it comes out it works normal, it will be a high -covered chicler failure, or use electronic device, someone can help me.
THANK YOU

If it is from 95 minimum it would have to be monopunto not carbonated, if you had injection problem your chek would turn on, of course if it is good, as I always say and recommend, it is best to perform a Scaner when the problem is Chek, now because of the symptoms that you give me that sucks me, to my parser the first thing is to make a tune, change of air filter, bench filter, spark plugs, spark plugs and cables The state of Catalan that is not covered, and if you can measure the compression, but I believe that with the tuning it will walk well.

I really do not know what the chek is that you tell me that it would turn on, and it does not use carburetor, the truth does not The revolutions remaining in idle, now you have to keep it accelerated until it warms up.

Well, if you can give me another recommendation, I will thank you the same, I will have to take it to scan it.

For the help borrowed, thanks, victor

The light that I tell you is on the instrument board appears as an image of a small engine or as letters that Chek Engine say, when you open the contact you will see this light, then when the light starts, this light must turn off, if you do not do it, you have a brother code, the problem of the relay is the fault of the IAC valve, or Relay valve. At some point to be the cause of the problem, it is not normal for you to start in three cylinders and then regularize you can have spark plug problems, or cables, now the problem of the IAC could give you a symptom like the one you mention, because in high revolution or working temperature it is deactivated or regulates according to need, it works like the Startel but Ees Electronic.
