Running a WAI through the wringer

[theholycow]

I wonder (if you felt like doing A-B-A-B testing again) if skipping P&G would help bring your IAT up. That might tell us if WAI could be useful in an xB but not useful with P&G in an xB.

I don't think you'll go rich/lean from any of this, even if you mess with the throttle body heater doohickey; I imagine that's well within the margin of error properly measurable by the O2 sensors, and if it's not then you'd probably throw a code.

Most all modern cars have coolant in the throttle body. It helps warm the air a bit, not much.

Personally, I wouldn't want a blanket (anything flammable) in my engine bay. If I was to insulate, I'd use insulation and/or foil HVAC tape.

You shouldn't be testing the HAI while doing EOC or P&G, how do you expect this to be anywhere close to a controlled test if you're mixing in those type of variables?
