The only thing I noticed was that when i wiggle the wires near the injectors it cuts out but there are loads of wires all masked up together so it could be any of them thats the problem. I take it it shouldnt cut out when you wiggle any wires no matter which ones they are?
Right you have a broken wire then, more than likely, get it to stu so he can diagnose it with the computer, ths will help find out what wire it is, DO NOT drive the car hard till this has been done
