CarloSW2, that is correct. The IAC has a 1/2" inlet hose, which is very easy to access. So, I drilled out a dime and stuffed it in the hose, right on top of the valve.

PLTW - I agree that a block heater is the better way, I have plans to install one. But until that happens, I'm reducing my warm-up idle speed (with this mod), and I've already put a resistor in parallel with the CTS to reduce cold-start enrichment. I have a knob on the dash, I can lean it out as much as I like when it's in open-loop.

Cheers,
