....what cause this collection of missfire?

Don't know since it is a 2.7tt engine. However, I do know that the first step in fixing the problem is very likely to be:

"Step 1 - Remove engine from engine bay"

Maybe you lost compression on a couple of cylinders there

You should do a test first

car still run normaly , just got first miss fire in cylinder 5 , and later this week engine mil come on again , and i find this , cylinder 3 and 6 has joined the family.

could be the cold weather we got lately had effect on them and they were at the end of theire life? (coils)


@ UrS4boy , well when i will have free time i will take engine out with gearbox for clutch change and some seals and gaskets leaking oil , but its not really that much complicated , its just if u want to change the turbos u have to take engine out.
