Re: 4.3 CPI Stalls in gear

Ooookay... So tonight's diagnoses provided a potentially interesting symptom change:

-The vehicle will maintain idle indefinitely in gear when the EST (Electronic Spark Timing) wire is unplugged thereby preventing EST adjustment.

-The vehicle will idle in gear from startup until the temp gauge has reached 200 degF.

From reading the FSM, it says,

"Controlled idle speed is always specified for normal operating conditions. Normal operating conditions are: coolant temperature in normal operating range, the A/C OFF, auto trans in Drive."

I'm wondering now if the IAC is stuck? Should I be able to manipulate IAC position by hand? How far out should the IAC pintle be when it's fully extended?

I wish a dealer service was in the budget.. Bah!
