I have had a progressively worsening problem with part-full load bucking it seems to be worse when the engine is cold.

I have tested/replaced the TPS.

Now I am leaning on the FI points being the culprit.

How are these tested? What should I look for upon visual inspection?

Any other causes for my symptoms?

here is what I have gone through trying to nail this down:

Ingition improperly set (mine is spot on to factory specs)

Possible malfunctioning vac adv (mine seems to function with suction)

Fuel pump/filter clog (my tank was recently acid bathed and has a new filter and a inline pressure gauge reads normal at idle and revs while sitting).
