hello help with Lantra J2

[lan19]

Good Morning everybody (at least morning Here)!!
I found this Site through googleSearch as I was looking for my problem.
So I hope that maybe I can read such interesting opinions for my dark problem...

My Hyundai Lantra J2 seems to have a problem but it is not appeared
anywhere.Any diagnostic machines show anything.

What does Lantra do?

Sometimes Without reason when you are in neutral position rpm goes down to 500 and less and up again to normal...after that engine stops.You must start again the engine and at your road to work when you press the clutch and go to normal-neutral it cant be hold even for 1ms and engine stops immediately.

Any opinions??
Ecu fuse and everything near this is checked and seems normal.I am sure it is power problem,not fuel,not air..

I also found that sometimes when You leave the hood down to be closed ,car loses normal neutral-going under to stop but not stopping..

However car has no other problems.It is super when driving.

Thank You for Your time

You may want to search for threads here or at RDTiburon.com, related to the throttle position sensor or the idle air control. Both of them can cause strange idle problems.

Do You have any Photo of these parts so I can Identify them on my car?
I dont speak English every day so I may Understand something wrong.
throttle position sensor= sensor when you press accelarator?
idle air control =???

Note that I own a 1.6L 16V Lantra Not a 2.0L(Unfortunately!!)

the idle air control allows enough air to pass into the engine to maintain proper idle speed when the throttle is closed.

you have the right idea about the throttle position sensor.

In the black bar near the top of the page, there is an item labelled "search" - click on it and search on those two parts and you will likely find more information than you can easily deal with.
