I have some good news and that is the car started earlier and sat there idling for 20mins then i drove it around the block, so its not the pistons thankgod! There wasnt any smoke etc or signs of it. It still sounds like its slightly misfiring though, its hard to tell as ive just put a .63 rear housing turbo on it so the exhaust note has changed alot since it took place.

Ive heard that the breather pipes can block and cause this aswell? I still have a standard breather system on it :/ Should get a baileys really!

Thanks for the off Liam and thanks for all the help lads.

Joe.
