Engine miss 1990 Buick 3800 motor 104,000 mi

Car will be running fine then it will start missing like a plug quit firing. It happens at slow speed or high speed going down the road. Engine rough, no power. Then it will pick up and run fine again. It happens about once or twice a day and I can go about 500 miles a day and it won't do it but once. Very intermittent.
No check engine light or no codes. It just keeps missing at any unexpected time then clear up until next time.
I installed new plugs no change.

It turned out to be dirty injectors. I can't believe 101 looks and no one posted a fix or suggestion.
