The proper way to diagnose a drivability problem is to isolate the system which is faulty, then trace and test each component until the offender is found.
Hunting by removing/replacing parts never works and only costs you money that could've been spent on an experienced technician.
If you've replaced the entire ignition system already, then you're either looking at one/more bad fuel injectors or a clogged fuel filter. It is also possible that you converter is shot. A severely restricted exhaust will wreck havoc on a engine.
And if smoke is penetrating the cabin, then I suggest you take your car into a shop immediately, because that is dangerous and could kill you.
