possibly an air leak on the boost hoses or knackered plugs.

have a nosey under the bonnet and check for any loose clamps or obvious problems

Hi

Does it do it when hot or cold???

Mine does it when it is cold....

But i would suggest plugs or leads as it has been known for the spark to be blown out by the boost and hence the mis fire. I had a similar problem with mine but i have put some ITV 24 plugs in and it has been fine..

Regards

I had this problem before its caused by reduced vacuum in the MAF, usually a side effect of "sock" filters.

Where has that piece of the plug gone? I assume its fallen out, I wouldn't push it much if I were you, if that section of the plug is still there, could cause a problem in the cylinder.

But then again, it may have crumbed in2 thousands of pieces and blown out the exhaust.
