EWP= extra load.
If this is something that just started happening, it's probably a loose cable or alternator problem.

it just started, I hope I find out the problem soon.
Yes. Check directly off the terminal on the alternator while engine is idling and it should read steady. If it fluctuates then more than likely the alt. is going bad. Check battery as well with engine running.

UPDATE :::
Checked the alt , engine off : 12.5 , engine running : 14.8- 15.0
I didn't find lose wire and I don't know the location of the ground wires .
I found the left knock sensor wire was cut !!! How to remove the sensor to fix the wire ??
is there any info where I can find all the grounds on the car to check them one by one ??

Shoebox's site should have schematics- www.shbox.com
Did you check the battery with the engine running?
I don't believe you need to remove the sensor to fix the wire. Is the connector to the sensor still there? If so, solder the wire back together with a piece of shrink wrap. If the sensor is gone hopefully you can find a company to ship one to you if there isn't a place available to you locally.

IDK, that running voltage sounds a little on the high side. The voltage regulator in the alternator might be causing fluctuation of the voltage and hence the flickering. I'd put my money on that as the cause.

Yes , checked it with engine running and got 15.0 .
The connector still there I didn't figure out how to remove it, but I need to because the wire is cut from the sensor itself. I believe I can find it locally.

Having the alt tested off the car might be a good idea, if there is some place to have it done. Some auto electrical shops might be able to evaluate it while still on the car. I don't recommend you replace it until you have some reasonable proof it is the trouble. Internet diagnosing is not an exact science.
