I have an H plate 316i Lux with an annoying misfire problem - can anyone from the hive mind help?
The engine starts first time and idles well - the misfire occurs at 1500rpm and then goes away at 2500rpm - it sounds like one of the cylinders has lost compression but a test proves otherwise
We have changed the leads and rotor arm already - I'm scratching my head now - any suggestions guys?
