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). |

You might want to check your harness where the wires enter the connector for the points. My harness was very brittle and cracking to the point where two of the wires were down to thin strands. I had been experiencing an internmittent bucking problem as well (mine was when the engine was warm though). I pulled the harness completely out and repaired all of the problem areas, reinstalled and have had no more problems.
