Urgent help needed!!! Voltage problem

You have 2 afm's yes? swap them and look for the same phenomenon... if it doesnt resolve with a different unit my instinct would be to start looking for vacuum leaks (sorry my knowledge on the AFM function is very limited).
You might find it runs alot better after you work through undoing alot of the fiddling you've done trying to track down the earlier problem
Is the cam stock? A aftermarket cam would make it "lumpy" or is it missing a cylinder? change your spark plugs and photograph them!!!!!!
What colour is the smoke, how does it smell, how much is there?

I also highly recommend replacing it with megasquirt. I did MS2 on mine, learn't a lot about EFI making it work and went a hell of a lot better too.

also after i took it for a test drive yesterday i noticed it was extremely loud but i thought it may have just been the way that engine sounded, but i put it up on ramps and stands and found the exaust just before the first muffler had a massive split (around 3/4 of the diameter of the pipe!!) so i took it off and welded a cover plate over it and that sealed it. so now its nice and quiet and runs a lot smoother i guess there wasnt enough back-pressure, but it still needs the spring to run
P.s i only thought of the spring because the original AFM is supposed to have an inbuilt recoil type spring inside the potentiometer cover and mine doesnt (from the photos i have seen anyway)
thanks to everyone who helped me out with this whole debarkle, the advice advice was very helpful!!
