Still Not Running Well @ Start-up

[North Coast Cab]

Well after a few days the car is still not running well at start-up. Really stumbles and won't idle. Revs a little like it s really missing, even giving it a little gas. Once it runs for 10 seconds it will idle, though fairly low. Once warm it runs great. Warm starts are great as well.

Here's where I stand.

Reinstalled stock chip
Adjusted idle back up with engine warm.

Checked mixture with voltmeter at O2 sensor. Was .86 volts, leaned out slightly to get more within range.

Checked Idle Control Valve
Voltage as specified across pins.
Removed and cleaned just in case.
I can hear the click of the ICV once throttle is moved

Head Temp Sensor
Appropriate reads when engine hot

Fuel Pressure - I don't know how to check.

DME Switch is set at #3
Should it be fully counter clockwise or to #1?

When warm idle fluctuates a little up and down, you can hear it more then you can see it.
