Hi Guys, My mate has an 1994 L Reg Seat Ibiza 2.0 GTi 8v. He is having problems with it wehn it is cold where it is really rough and splutters but once been on for a couple of mins seems to settle down a bit. The ISV is buzzing and it stalls when it is unplugged. I'm thinking it may have an air leak somewhere. I no its not really a VW but hope someone can help so we can have a look at it tomorrow. It is also chucking out a lot of black smoke when its booted. Thanks in advance for any replies. Cheers Nick
