Alright folks,

my cossie has a missfire to it, heres what i have done to check her out :

put 4 new plugs in the car
new ht leads
checked plugs sparking by attatching them an earthing them - all fine


I had the car parked up for a while after it started running rough last year.

I started her again today, first of all she was missfiring as usual like before.
However no 3 lead wasn't doing anything sorta thing. While its running i can pull off an reconnect lead no 3 closest to bulkhead of car and it made no difference.
I then removed plug no 3 and this was a brand new plug i'd just fitted 5mins before, it was now black and sooty from the top, no oil or wet just black an sooty.

Also when i started it today, i found it chucked blue smoke out on startup and as i rev'd it smoke came out. But i now find the smoke has stopped being blue and on idle the smoke coming out whilst missfiring is black an smells of fuel.
I also noticed while running shes had black sooty smoke appearing from around the turbo downpipe that attatches to the turbo, so there was some smoke coming out whilst it was running an missfiring away

Can u guys help me diagnose it, as i'm not to sure at the min

cheeRS in advance peeps
