It's not technically a Skoda but-

My mums VW Polo has developed a fault, it's the 1.2L 3 cylinder engine (sure they must use it in the Fabia?) and it's mis-firing basically and has no power (well, even less than normal).

The engine warning light started flashing at first which according to the handbook means risk of mis-firing damaging the cat.

Now the light is on permanantly (handbook suggests lambda fault) and the engine misfires.

Anyone got any ideas? is this a common problem on that engine?

I can only guess that it's either the Lambda sensor or a faulty coil pack? or pehaps something really simple like a knackered spark plug.

i've heard that these suffer from coilpacks going wrong.

Coil packs do seem to be popping up (was mentioned on here a short while ago).

The cars just coming up to 4 years old now, it's gonna be replaced soon so I hope it is something simple like that, any idea of the cost?
