I think bucking is a classic symptom of a lot of things.  The AFM
fix is probably the last thing it would be.  Though I guess it does
get worn out (especially if LOTS of driving at a constant speed).
You can pop the top off it to give it a look.  Investigating my
bucking last week I took a look at mine and it had already been
rebuilt (my van may have been pieced together).  Anyway, what
I found to fix the buck was that the temp sensor on the #3 head
was loose.  This caused the ECU to intermittently richen the mixture
making the plugs miss and the vehicle to buck I suppose.

Good luck,
