Hello everyone, 

Must say that on this forum I'm writing only when have some sort of a problem, but in addition to that must say that Briskoda is one of the best forums out there. 😊

So, if you guys could help me again or just give me honest opinion once more I would be much appreciated..

As title says, it's a 2007 Fabia 1.2htp, BZG is the engine code with some 100k miles  on the clock. In past several months I'm noticing like the engine is missing but only at idle and it's like slight judder. Drives just fine and obd11 scaner is not showing any codes. 

I was wondering could it be that coil packs are on their way out? 

What's your thoughts and experiences?

Hello, I'd suggest pulling the plugs and check their condition and gap first. Use a proper coil pack extractor so as to not damage them when removing.

I don't think that the spark plugs are culprit, have two sets of used ones, Bosch and NGK, in good condition with gap properly adjusted and same thing is happening.
