Just thought i would resurect this thread rather than tying it all again.
After a very long time and lots of help from Al, serek and other members, I believe we have finally got to the bottom of engine problem. The problem was i kept getting p0130/p0150 also car felt like it was trying to stall. After changing all of the above plus cambelt,cats,02 sensors x4 all bosch orginal,we decided it must be the loom so i got Al to change this and after a very long day the car then broke down on the m25. Al then spent several hours at mine soldering in new plugs trying to solve the new issue as per Als thread last week. This didnt make any difference so decided to put in another wireloom.So once again Al spent another long day at mine installing another loom, It worked

It looks like after a 18 months i have a car that works.
Sorry for rabbiting on but if it hadnt been for the people on oof this one would have been scrapped.
