Bloke across the road is having problems with his Astra . It's an estate 1.6 on an S plate .
We aren't sure of the engine code on it ?
We have looked at topbuzz for code reading results but can't seem to match the ecu up .
We think it's a GM Multec ?
but it's coming up with code 103 but there is no 103 on any of the code reading sheets for the various ecu's on the astra .

The problem it's having is a very poor spark on 1 and 2 cylinders .
Could this be down to the DIS pack or an ecu fault do you think ?

Thanks .
