you could try fitting a suppresor after the alternator as you may be getting voltage spikes which can cause some crazy gremlins in your elastitrickery system and will cost you all of a fiver.
today I've fitted new rear discs,pads and re greased rear wheel bearings. cleaned up my callipers and fitted a new rocker cover gasket. not bad in 2 hours if I do say so myself.
mines not too bad I suppose just needs at a glance
