RPM drop

Hi gyus,

I have problem with my 2012 Fiat Punto 1.4 8V (106k km), basicly it is doing what's on video. (can't post URL right now)

The video was made while moving in a traffic jam, the RPMs drop more than it should, so the shift down sign appears. MAP sensor and throttle body has been cleaned, not much of a change...

I get slight periodical vibrations on idle with warm engine, even more with lights on...could this be an electrical problem?

Could it be the plugs? wires? coil pack?

Thanks for any advice.
