A piece of kit that is invaluable on a car with engine management systems. I’ve had mine for years and these days only cost about £20. On other cars I’ve had the reader has usually pinpointed any faults and made repairs very straight forward.
This showed the P0353 misfire fault which in this case is not so straight forward as there are quite a lot of possibilities causing the fault. So i am working my way through them – easiest ones first. Starting with changing spark plugs.
