Have you checked your plenum gasket. If it was really bad it could cause some of those symptoms. You should also do a compression check on your cylinders may have a burnt valve.

you may also want to check the plastic busing on the top of the distributor plate. If that comes loose (plastic bolts shear off) then it really messes with the fuel sync. Also want to check the drive gear on the camshaft that drives the distibutor. If that is badly worn and there is play between those gears, the same thing can happen.

I'm having a similiar problem. I'm almost sure it's a mechanical problem. I hope I know later this week after I work on it.
