Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

I recently tried the paper clip trick to read the fault code on my Corsa B 98 1.2 8v... It gave the fault code 43 - which is (Primary ignition (distributor systems) High voltage)...

Does anyone know what is causing this fault or where i should start to tackle this fault?
The fault appears after around 20 mins of driving and resets itself once the ignition is switched off.

Any suggestions will be very much appreciated.

Cheers.

hmmm not sure mate. all id think of isit the correct battery you are using? sorry not much help

The battery was installed and used long before the fault appeared so I assume that the battery is the correct one. Thanks for responding though
