Bad alternator and bad running..

[AL92]

I have a 90 talon tsi .When I got the car it had a problem with surging and bogging and not revving up very well. It got worse and worse. I started doing some maintenance stuff,new plugs, wires, fuel filter,walbro 190, swapped injectors from my other good car, new 02, swapped ecu but car runs worse and worse. I can't even really get any scan info on the car anymore it won't rev past 1000 and it stalls out pretty much right away it sounds like its running on 2 cylinders. So could the alternator be wreaking all this havoc. The car is also flooding out pretty much right away and the fuel reg checks out fine.
The injectors are fine. The plugs are wet with gas and the car don't rev up at all. Its not boost leak we have checked for that.

So once again could it be alt. These cars rely on power pretty heavily to work the computer and everything.

Anyone had similar problems and it was alt.

whats the batt voltage? A quick way to see if the alternator is charging is to remove the neg terminal while the car is running. If the car dies as soon as you remove the cable than the car is running off the batt
