Problem solved,it was bad grounding,now i have another problem,when i start the car it seems runs on three cylinders,after driving a while (1-2 km's) it works fine,and when i stop the engine for 1-2 min's it make same thing,changing coil packs doesn't make any difference all of them works,when i unplug 2,3 or 4 cylinder has big difference,but when i unplug 1'st it has small difference in running,when it works bad have no power and sounds similar to boxer engine sound,any ideas?

Bad ignition amplifier is the most likely cause.
