If you soldered the wires IN the afm they should be fine. Unless your mechanic can't solder vary well. If its to much fuel, which its possible, but also possible the other way around, but if there is to much fuel, you could tighten the spring in the AFM.
Another check you could do is go under the hood and try to slowly press the throttle till you hear the engine start to bog, then manual try to push the AFM flapper open a TINY TINY bit and see if the engine come back to life at the throttle amount you are at. This would say you are running lean.
Tightening the spring would cause you to run leaner, and loosening the spring woudl cause you to run richer. Can't loosen the spring to much though, couple clicks and thats it, otherwise the flapper won't shut all the way.

Unbolt the AFM from the airfilter assy.
There is a cover made of plastic and has a somewhat *D* shape to it. Basically about 3" x 3". It has a bead of clear RTV around its edge holding it in place. Take a razor blade and cut the RTV, then put a Small common screwdriver under one edge and lift the black plastic cover off.
I'll stop here and let someone else continue. I'm not comfortable describing this unless I can attach a jpg of the afm guts. Can't do that now.
