coil pack ;)

do you have a loss of power?
is the vibration more noticibable at low speed/revs but always there?

check for a spark at each plug

could be the wiring but check the coil packs first.

This vibration effect isnt actually specified on the fault finder for the DOHC, might be a good additon?

I dont think the Lord Almighty is a great car fan ;)

They say he moves in mysterious ways but I dont think that is caused by worn ball joints and bushes ;)

Apologies ;) couldnt resist, your English is very good, better than my Swedish anyway! ;)

Can not find any faults on the coil-packs. They give sparks to all four plugs.
The vibrations are at the highest level when I use the Cruise Control,( trying to speed up.)

hi there

might well be an air leak at the egr valve or on it's pipework.

the the egr works at part throttle, so might be making the car running lean.

btw, even if the coil packs are producing a spark, they can be breaking down under load. can you change one for a know working one to check?

hth

Tried an other coil-pack.( Just one). And changed the EGR-valve from my spare-car.
But without anything hapends.( Not a new one). (The FMD-was closed.)

i disconnect one coil pack at a time just to see if it will fire up, it will run on two cylinders but dont do it for long
