i think i have solved the problem i put a dry spark plug in and took the injector clip off and took the lead off aswell then i ran the car for about 4 minutes when i took the plug out i found that it was getting wet with oil proberly runnig down the valve so i have took the cylinder head and there seems to be a bit of play on the exsuast valve so i am sending to burton power to have it checked out i will let you know what happens
happy new year
