89 Kick - Cold start gas pedal feathering annoyance

[thuston]

89 Kick, 8V, 4x4 , AT, 195K, Cat removed by PO

- Getting immediate 12V at Dashpot VSV upon start, no matter how cold or warm.. Dashpot gets immediate vacuum at start.. VSV tested manually and works fine with 12V applied and removed.  Clicks heard, and air test thru filter works perfect.
- ECT Sensor replaced and tested. ECT tests good
- IAC Wax pellet is bad.. 1/2 OD host routed with no vacuum leaks from IAC intake to inside dashboard to manually switch IAC on/off.. I use a golf tee to plug the hose once warm and idle can drop to 850.  Works well for me.
- When starting cold, IAC gets air to intake from hose , but must feather gas pedal to add air to start.. Then feather for 15 seconds till IAC can work alone with air coming from manually controlled hose to intake from inside car. Franken IAC replacing thermal wax valve  
- If I pull hose at VSV to disable dashpot vacuum, and add air to intake thru hose, I still must feather gas to start when cold
- If I pull VSV hose to dashpot when car is hot (remove vacuum), Idle goes to 2500ish so dashpot works as it should.

Car idles 850 hot, 1100 with lights on (ISC controlled)..  
Cart starts fine hot with no feathering of gas pedal.. Life is good once hot.

Any ideas why dashpot may be getting 12V at all times car is started?   ECU maybe?  I have not checked Caps yet, unknown if PO changed caps, but could this cause this issue.. No other issues ECU related 
Any ideas why the need to feather gas still if (Intake is getting air from hose and dashpot vacuum is manually disabled?

Thanks all..  Enjoying my Kick in Arizona
