Hi my son has a k12 micra 2003 1.2, we have noticed that the car when warmed up will when at traffic lights or slowing down the battery warning light comes on and the engine just ticks over and will not rev then just dies no other light comes on it also happens if coming off a motorway you take your foot off and the engine just idles and will not rev the battery light comes on then stalls. has any one else had this problem thanks. i have had a diagonostic done on it and it comes up with timing chain otherwise car runs fine
