The misfire seems to be alla the time when is cold. The valves are new and the engine doesn't burn oil at all.
I will check the spark plugs soon and the compression too.
I need some days to find time to check that. I will post the results as soon as possible.
Thanks a lot

Intermittent electrical problems like that can drive you crazy -- good work finding the cause. Thank you for updating us on the solution!

I did wonder if it was the low voltage wiring in my post on the 29th. The issue is when cold you need a better spark and when cold, the battery gives less output, so all you need is a resistance joint (or some leakage) and you get a misfire.

Good news that you found the problem.If it is still only cylinder #2 then it has to be something specific to cylinder #2, but in the last 12 months you have changed most things, so here we go:
- We know the car is 2005, but how many miles/Km?
- It could be the low voltage wiring to the coil or a bad connection on the coil on #2, check the cable and connector for any signs of damage/dirt.
