cold start problem - interim report

[Fourkguy@aol.com]

86 4KCSQ - constant stall at start up until finally holds ignition.

What I've done so far:

Repair fuel line leak caused by corrosion.
Replace Coolant Temp Sensor.
Replace all plugs with Bosch Platinum +4 4 electrode plugs
Replace cap & rotor
Check for vacuum leaks.

Current status:

Much improved. Car starts on first try but stumbles until warm. This happens 
hot or cold when the car has been off for more than 1/2 hour.
Could it be : Leaky injector?
               Fuel Pressure accumulator?
               What else??

Please point me in the right direction.

Thanks,

Jeff
