I just went out for a spin and it happened again when I was at the lights. It sits one notch below 1000. When I got back home I put the AC on again and the revs started bouncing and then dropped out altogether, do you think it's likely to be a battery issue? It takes literally 10 seconds or more on the key to start when cold. It seems ok when I put the lights on but there is only one working at the moment. My worry is that if I've been sold a major lemon im put off to spend more and more just for more problems to occur or be discovered.
