had a problem like that, drove me mad, checked all the usual, fuel and spark related. After banging my head against the wall for days it turned out to be the earth from engine to chassis etc. I know it sounds daft but if you havent checked this, replace these earth straps and get a good earth. my missfiring went, good luck.

[tcpc]

where should the earth strap be or where is it on your car

i had one from battery going to bolt on the engine lifting eye just by the bell housing and then to chassis bolt, and one from alternator mounting bolt to the coil mounting bracket. Replaced these with black earth cable from halfords also cleaning around bolts with wire brush. Hope it works, also when its dark rev the motor and check for arcing.

A quick way of checking this is to use a single jump lead from the battery to the engine/chassis.
