    Possible vacuum leak M40b16???

    Hi all, My 1990 bmw E30 (M40b16) has been barely drive-able for quite a while now and i can't figure out the problem for the life of me. It runs really badly on start up and splutters a lot at idle but after 5 mins or so the idle becomes a bit better but it splutters a lot under load and acceleration, also the plugs are completely black even after only running for 5 mins. I have replaced Spark Plugs, Plug leads, Distributor cap and rotor, Ignition coil, Air filter and all the gaskets for the intake manifold but still nothing. I'm assuming its running rich due to a vacuum leak but i wouldn't have a clue where to start on these Older BMW's as i'm reasonably new to them. Anybody have any idea on how to find it/ best places to look? Cheers
