John, I have just been through a bunch of similar hassles. Here's what I did.
I looked around AND moved around various hoses on and over the engine. I found a
vacumn line was off it's connection. Reconnected it. I also discovered the
crankcase vent line had rotted, so what ever pressures - positive or negative -
were supposed to be maintained in the crankcase weren't. Replaced it. Engine
smoothed out considerably. Additionally, after warming the engine thoroughly, I
disconnected the idle stabilizer valve, and adjusted the idle speed to 900 rpm.
I also cleaned the ISV with carburetor cleaner. Reconnected all for a cold
start. it started easily, idled easily and smoothly. Went for a drive, and the
engine bucked a bit, especially at partial - like feather footing the throttle -
throttle settings. even bucked a bit whe of throttle completely. Disconnected
the ISV and drove again. Smooth as silk. Obviously a problem with the ISV or the
ISC (idle stabilizer control - right side behind the tail-light assembly.
This I have not resolved yet. So on a cold start, I to have to keep a little
throttle on it to keep it idling until warm. If I start of too soon the engine
tries to bog down or stall. Just typical cold engine without the benefit of any
cold start fuel supply.( read "enriched" with extra fuel.)
I would give this a go before doing anything else. If you still have a problem,
I would be suspicious of the Temp II sensor.that mounts by the thermostat jus
forward and to the left of the engine.
Good luck.
