Hey guys, it's been a very very long time since I've posted but I wondered if anyone can shed some light on the mess I've got.

I've got a gti that I have just done the head gaskit and cam belt on it. I bought the car with the head gaskit blown and running rough. Its all back together properly but it has a bad misfire and when testing the ht leads cylinder one pulled off makes no change cylinder 2's lead makes it misfire a little more but cylinder 3 is going mental and sparking to anything and everything. I have changed spark plugs ht leads and coil pack and it makes no change. Errrr please help I'm losing the will to live. Any help will be welcomed thanks a lot guys

Maybe its out of time. Checked camshaft sensor?

Silicon Grease around the ceramic of the plug will help this - very common problem on the zetec and this is what Ford used to do to prevent this.

Thanks for the tips guys ill start looking and try these out see if it helps

worth doing a compression test first

Compression testing was on my list to do aswell I'm just having problems finding one that can get down to the spark plug holes as its quiet a deep head. Even if it is lacking compression in a cylinder would that cause the bad sparking.
