MasterThis car has DIS, Direct Ignition System, there is an ignition coil installed to the top of each spark plugs, so there are 8 ignition coils all together.
There is no distributor cap and rotor.You can find great repair manuals with step-by-step instructions, diagrams, parts locations and other important information here: http://www.eautorepair.net/Marketing/Default.asp?VID=125669

So I'm guessing I have a carburation issue then. She runs a little rough, better after warmed up. Thought maybe I had week ignigtion but not likely with this system.

No carburetor, It has a fuel injection system. I'd check spark plugs (make sure there are no Bosch Platinums are installed, if yes, replace them with NGK plugs), fuel filter and fuel pressure, Intake gasket leak, Air flow sensor.
The best thing would be to take it to a BMW specialty shop and ask them for a diagnostic. They can run a complete diagnostic test on it.Zee
