Hi,

A common problem with the focus from 2005-2011 is the rubber seals around the windscreen washer jets deteriorate as rubber does in general;

This issue affects the 1.6 petrol engine because the location of this particular engine positions the spark plugs in line with the leak.

This allows water to enter the rocker cover which then gets in to the coil packs and can cause the misfire,

I recommend using some bathroom silicone sealant to seal the area around the windscreen washer jets; under the bonnet even as preventative maintenance because it is a known issue. 

Hope this helps, fitting a Volvo engine cover also stops the water getting in there

+1 for the Volvo mod, haven't had any real issues without, but have had a couple of times I've noticed it a bit wet in there with my last 06 plate. Felt it better to get it and not need it on the 58 and made sure it was one of the first things done after purchase.
