Sorry for the long thread but i thought id give you as much history as possible so you know what im dealing with suggestions on this would be much appreciated jim

Jim, I used to work at Baileys Nissan in Canterbury so can have the use of Consult when needed. I've also got another Zed which I can use to swop bits over to try out if I need to. Where you taking yours mate?? Are they someone you know?

PS, Car really bad tonight, starts at about 4000 rpm then just holds back and kangaroos. Worst ever! I'd rather the bloody thing broke down at least I'd have a chance of fixing it, these intermitant problems are a Bast**D.
