'165 Minimum Air Question...

[Bob Valentine]

Since it hasn't been mentioned, (and probably the next question...) the
easiest way to extend the IAC is to put the ECM into paper-clip test mode
for about 30 seconds, then disconnect IAC.

Side note unrealted to this thread - don't try and use a 3.1 IAC on a 454
TBI throttle body.   Pintle diameter is smaller on the 3.1, pintle will pop
out of IAC motor when extended....
