Ok, will do... will keep everyone up to date.
After the overwhelming number of people pointing towards an ignition coil im going to leave the ECU where it is.
Ordered the ignition coil, 25% discount. £27.85

Tomorrow I'm going to attempt to replace it myself, haven't got my Haynes manual through yet, and I'm pretty useless...
But I'm going to try! (I'm sure i can find a guide on here somewhere?!)
After this doesn't work i'm going to take out the ecu (reverse psychology

)
