M30 Missfire

I have acquired a 3.5 M30 powered e30 which is misfiring, any ideas what it could be?, what are the best and worst case scenario's?

Thanks

Is this a blue carbio ?

I'd check for

Spark
Fuel

and

Compression

in all cylinders.

check the dizzy cap very carfully too. they tend to crack in odd place's causing arcing.

Thought you was dead against the anchor Fal?

First thing is to determine whether it's a particular cylinder (or cylinders) that isn't firing, or a random misfire. Ideally, you should short each plug lead to earth in turn, but pulling the cap off doesn't usually cause harm.

Happened to me and I would NEVER advise anyone to do that

If you're daft enough to do it with your fingers, then you deserve what you get!

Buy a pair of proper plastic pliers made for the job
