Rough running
HI all
I'm new to this forum I have a Porsche 911sc 1981 I have a problem with starting and running, it starts then dies when I push accelerated it will run but back fires and rubs really rough when I stop revving it dies straight away. I've noticed I have 24 volts at + side of the ignition coil is this normal? I thought it should be 12 volts. Any ideas please

Welcome aboard.
24 volts? Hmmm. Check to make sure your volt meter is reading correctly. A Buddy with a 78 bought a new volt meter and it was off by 4 volts. Check what the battery is at too.

Thanks for the welcome. The meter is ok I have another and it reads the same, the battery is new and showing 12volts I'm very confused too. I'm thinking it's possible that the CDI box is faulty
