Sorry, I know this is a repeated subject!
I've searched through, and there are loads of threads, all with misfire issues. So far, I've figured it could be one of 2 relays, the MAF, the hall sender, the lambda sensor, the plugs, leads, dizzy, or dizzy cap.. So, what is the simplest way to diagnose without spending cash on all these parts and replacing on by one!
We could really do with a misfire diagnosis FAQ, perhaps with pointers on where all the things are in the engine bay, and guides to checking them..
