hi recently my 1.4 12v bravo has been playing up it will start fine then when you drive down the road every so often the radio will go off the airbag light will come on the rev counter and speedo needle drop and a couple of times its even cut out but then will start again straight away. has anyone got any ideas wot it could be the battery was changed about 3 months ago so i dont think its that. Any help would be gratefully received thanks

Have you checked that both battery terminals are on tight?
