O2 or Temp 2. Easy test, if turning the key off and on makes it run
normal for 30 sec or so, problem is O2 circuit.

Subject: SERious Bucking after warm up...

I guess, it is my turn.  For years I was reading of this menace and now
I am baffled.
One thing I did and installed that foot long addition that is supposed
to take care of it.
BUCKING did not stop.  And it is violent and powerful.
I wonder if a check list has been developed by now.
I am assuming that by now we know where to start and carry on until the
culprit is found.
I feel helpless, yet I know the List will come and fix it...
What shell I do?
