In all the years we had a 2L with trigger points (10?), we never found cleaning/lubing/etc to them did anything. The only thing that worked was putting in new ones and generally that was done after everything else was adjusted, poked, replaced, etc and the problem never went away but new points "magically" fixed it! This may be against what many will say but the replacement ALWAYS fixed the problem.
Since you said the O2 dropped low, I would suggest installing a fuel pressure gauge and run it up through the engine lid so someone can watch it. The engine is a bit larger and it sounds like to me there is not enough fuel being caused by pressure surges. We used a gauge that was left in all the time and now and then I would run the pressure up and down just to "clean out" the pressure regulator. Seemed to help. A note, if you unplug anything, make sure the hoses are well plugged so an air leak does not mask the issue. |

I do have a fuel gauge in the cabin it holds steady @30psi under any and all conditions, needle dosnt even wiggle. Im thinking trigger points |
