I just solved my bucking today having found my cylinder head temp sensor
was loosely screwed in.  Mine bucked at all speeds, but in particular
downshifting as well as the upper end of each gear.  It also became
difficult to start.  I think this flaky temp signal to the ECU was causing it
to go rich and in such conditions my plugs were unable to fire.  Replacing
the plugs, cap, rotor, and wires, always helped the problem but was never
a permanent fix until I found this loose temp sensor.

Good luck,
Christopher Darilek
