My '87 3.8 Bonneville has a low rpm miss. It is most noticable when the torque converter kicks into OD at 50 mph. It has a slightly ruff idle. A bit of a miss on start out. But runs very good otherwise. There is a new crank sensor, cam sensor, oxygen sensor, and MAF sensor. I have serviced the EGR and checked for vacuum leaks. There are new plugs and wires. Any suggestions?

the next step you should take is to check the compression of the cylinders. they could be enough to start and run, but not enough to run correctly
