Yes I did think that, I suppose there was a 4 in one chance of fitting that same injector to number 4 cylinder, I will be fitting 4 brand new injectors when the engine returns, but I am still not fully convinced that will be the end of the matter, I have spoken to all sorts of people about this and no one can really assure me, Engine wiring looks good and like I said could it be the ECU? But no one that I have spoken to thinks in could be.

Thanks,
Lindsay.
