Coil pack? Won't be the fuel filter, its got a 150k lifespan.

Could be coil pack, TDC sensor or the oxygen sensor.

The coilpacks can let moisture in causing the miss-fire. As for showing on the dash I'm not 100% either way. Try disconnecting the HT leads 1 at a time and see if it makes any difference, remembering the order of them though!

TDC sensor is another possibility and it's about £30 from dealers I believe. Plenty of threads on here about it.

Someone I know had a 1.2 16v with miss-fire and shuddering problems. It was eventually diagnosed as the upstream oxygen sensor which set them back close to £200 at the dealers.

Check the carbon canister miaybe its bust.

Check the temperatrue sesnor and the TDC sesnor one of them might have failed easily also check/clean the throttle body.

Fuel filter as said is good for 150k.

Doesn't come on the light.

Coil packs are £30 or so easch a set is £120 in theory since the 1.2 uses seperate ones.
