Managed to get home slowly & checked NGK plugs & Coilpacks & found when No1 coil pack unplugged no differance to Engine ...so must be Coilpack or plug ??? ...Pressure tested Cylinders also !!
Was praying not head gasket !!!!
Anyway when I had a look around Noticed multi plug on No 1 fuel Injector looked more proud than other 3 So pushed it back in only to find it pushed back out !!!!
Turns out underside fixing clip was snapped off & plug wasn't touching correctly ...a quick cable tie around No1 injector & between injector plug two wires ....Sorted .....thankGod .!!!!
To sort 100% would need to sort new plug onto loom .... ....it's good for now ....
