930 stumbles on acceleration

My 86 turbo will stumble and belch black smoke when I roll into the throttle at about 2500 rpm.
It also runs rich at idle and failed the local smog test.
I pulled the air cleaner and I noticed that the CIS sensor plate 'flutters' at idle.
If I steady the plate with my finger, the idle smooths out.
I have aquired fuel pressure testing equipment, but I haven't gotten around to doing it yet. I'm hoping it is low fuel pressure.
Any ideas?
