hi guys

I Have changed the sparkplugs and coils today but it still is the same.
I Hope it is not the headgasket! Could it be the injectors or ECU?

The fault codes that i was given are
cylinder 1 misfire
cylinder 2 misfire
cylinder 3 misfire
cylinder 4 misfire
cylinder 5 misfire
cylinder 6 misfire
random cylinder misfire

I also went out in the car today and noticed that i can drive the car normally for hours it drives 100% perfect also checked the oil/water levels
and temperatures all okay.

Now say if i am in 2nd gear plant my foot down, only when revs reach
2000rpm-3000rpm it misfires, it will not misfire after this, if i hold it at 2500
rpm it will misfire really bad and engine light will come on and it will continue to misfire even at idle until i switch engine off and restart
where it will clear unless i produce it again.

After the engine is restarted i can drive off as normal without any problems
until i plant my foot down.

After reading up all night on the vanos system and different issues on it
it seems that vanos will only cause rattles and not misfires, i dont know
if this is correct???

If it was injectors will it not misfire all the time?
