I have a 93 520 (e34) (m50) and it has a misfire, Ive checked the plugs and they seem ok, what else should I check.

not sure on your car does it have coils on top of plugs? I had a misfire on my 3 series 00 it was a bad coil replaced it and works fine now. 2cents worth used

Have you checked the HT leads and the distributer cap to make sure each cylinder is actually getting a spark? Is there any blue smoke from the exhaust cos that can be a sign that incorrect combustion is occuring within the block

Fit a new set of leads and hopefully the problem will be fixed..........if not as others have mentioned move on to the coil and dizzy.Someone with a smart-scope would quickly identify where the probelm is for you,and would only take half an hour to do so.

Good Luck.

Its the later type leads, not the usual dizzy cap etc, theres no smoke on start up.
