On rainy days - when I start car (parked outside), it gets shaking and there is less power like running on 6 cylinders (only when its raining or wet). Spark plugs are new. Coils work or don't work i suppose there is not some midle option? Ive tryed to spray coils and cables with water, to see if that is the problem, with electricity going on housing, but it wasnt.

Could it be some computer in car, that tells coil nr.6 to turn off because of moisture for approx.5min and than back on? Or something like that. Coil gets back working when car gets worm and/or I start it again. So I think it could be somekind of reset of computer that later helps running on all 8 cylinders.

I saw the seal on valve cover (on top, under air filter) is not perfect?

When there is no moisture, car works great. :surrender:

Thanks
Mark

Did you check the lambda sensors?

If one of oxygen sensor is broken, could have a similar problem.
