Remove coil pack and check plug wells for oil/water  :y

there is a small amount of oil but not much could this be shorting out

Yes, this would suggest that your cam covers are leaking.

And that the cause of the leaky cam cover gasket is blocked breathers  :y

You will still need to change the cam cover gasket......use genuine Vx

The blocked breather would have caused the cam cover gasket to leak, did you clean all breathers including the vertical metal one bolted to the sump?

Edit: did you follow Auto Addicts' Maint Guide?

You need to have the codes read, where abouts are you?

Could be cam sensor failure.

When they did the diag work, did they do any actuator tests.....

.....coz they should have done!

It possible its a sticking EGR valve which would have shown up during actuator testing.

Hi - i am having the same problem on a 2.2 y22xe engine - 2000 cd model - replaced the cam gasket due to oil around the plugs and changed the airflow meter and still no change
I would be most interested to hear if anyone has another solution.

I don't know if this makes a difference but if i fill the car full of fuel and drive a distance down the road it will try to cut out loose power and missfire until the fuel level is below 3/4 of a tank???  - I am told this could be a dodgy fuel filter stopping the fuel flow.

Cheers Rjay

Seeing as your gasket leaked, did you also clean your breathers
and throttle body which is one cause for the gasket to leak?

See this 2.2L guide by Auto Addict. Pay particular attention to the
comments and picture at the end of the post.

http://www.omegaowners.com/forum/YaBB.pl?num=1162397695

I doubt the full fuel tank will cause cutting out. The only thing this
could possibly do, is maybe put fuel into your purge line to the
Throttle Body. But I would have to see how the lines lay to form
an opinion on this, plus any fluid traps built into the system.
Maybe someone who has delved deeper into the layout would
care to comment?
