I think i will try the ht lead swap! (if i can get home at the weekend... lot of work...

)
Im not sure about the valve (after 325000 km, i can not be sure...), but i've made compression test, all of the cylinders were 11.5 bar.
Ernie! I was thinking just the same, i've tried the cheapest thing first (sparkplug)!
ps: This fault was a little bit weird, becouse i went home in motorway (half an hour driving with130-140km/h), the car was ok, just like in the last 14 years. An hour later i washed the car and wanted to go to paint shop to buy paint for the car (little bit ironic). I've started the engine, but only 3 cylinders were working (sometimes 4). first i thought its becouse of the wash, but the engine and the surroundings were dry...
