Any stored codes in the engine computer?

Might check the Air Flow Meter and make sure the connector is snug:

I had a missing issue with my '85 at certain RPMs and finally it threw an AFM code and I found a loose connector at the AFM. Fixed that and all works fine now. Missing was due to the fuel pump cutting out a little and the fuel pressure dropped.
