Technical Poor acceleration, 'spark' clicking and Engine Rumbling

[amcnab]

Hi all. Attached is a video of what I think could be the problem, but not sure what these parts are?

My Fiat Panda 2004 mk3 1.2 is struggling to accelerate and the engine is 'rumbling' at idle. When I do try and accelerate there was this 'clicking sound'. I idled the car and opened the hood and saw that there was this 'spark' between these two 'wires'.

Can anyone tell me what these two wires are? Picture also shows expanded view and circled the two 'wires'.

What could be wrong?

One is the HT lead on top of the spark plug
The other Breather hose


It is possible that the HT lead has been damaged and it just needs a new one

But it's more likely the gap is too big on the spark plug and the HT voltage is finding another path to earth the breather hose


When were the plugs last changed

What is there gap they start at around 1mm and start to fail at around 2mm


Needs sorting as soon as possible, continue to run the car will eventually kill the coil
