Bang Head Missfire under light load when hot

First let me say my 87 GN is the most trouble free car I ever owned (I bought it new). BUT it's started to missfire under light load and only after it reaches operating temp. It's fine under full throttle and before it gets hot.
It's also started upshifting to 4th directly from 1st on occasion. When this happens the converter also locks up.
I put on a new coil pack only because that and the cam sensor loosening up are the only 2 things that have ever gone wrong with it in 22 years.
Anyone have a similar problem or any ideas?? Thamks,Mike
