Then if the missing is unchanged, then this points to a mechanical cause.

Edit: Anybody has an MSD-DIS4? I believe these units are supposed to increase dwell in the lower rpms.

I haven't been following this thread too much as of lately, so I dont know if this has already been covered...

Have you tried just unplugging your coolant sensor? When I got my tranny swapped out a long time ago, the guy forgot to plug in my coolant sensor.

The car still ran fine even though it had a CEL from it. I took it to my mechanic, and he said that when the coolant sensor is unplugged, it will feed the ECU a preset/default temperature so that the car will still run.

Just a thought, dont know if it will help or not. He had one of those big OBD1 code readers, and it gave him the actual default temp it would give to the ECU during that CEL. I just can't remember the exact temp. That was almost 3 years ago.
