It cuts out and bucks doesn't completely die and doesn't do it constantly mainly at lower speeds and when accelerating but occassionally a small bobble at highway speed. Missing when idling. It it a B21 engine with mechanical injection and the MPG ignition with the white distributor cap. I have:
Replaced large fuel filter at firewall
Checked plugs (no fouling, look all the same color, etc.)
swapped in known good plug wires and distributor cap.
ran tanks of gas through it with Seafoam injector cleaner also Heet.
Main fuel pump was replaced about 30,000 miles ago
In tank pump replaced 10,000 ago

Checked coil resistance from main plug to terminals 10.6 ohm (not sure what it should be)
Not sure what else to try any suggestions would be greatly appreciated.

Thanks!
