Might check the stabilization bypass air tube for cracks and loose fitting.
If to much air is slipping around, that to can cause it to stumble. My 84
Q developed a crack that was were hard to see, but finally got bad enough
for me to see the buckleing when it let air in, which cause the engine to
stumble. Duck tape worked for awhile, but I finally replaced it. ---JCG.
Good point! I fergot about that. I also replaced that funny
odd shaped tube when I had stumbling problems (actually it
was the car, not me) in addition to the OXS and fool filter.
