165 $6E cold idle

[Marteney, Steven J.]

Found my idle problem this weekend... cold weather.  The weather here (East
Coast FL) went cold for the first time since I started playing around with
closed loop disabled.  Both my lean and rich chips ran like crap.  This
weekend, both chips ran great.  The lean one's idle was a little rough, but
not that bad with the low end of the MAF Scalar table turned up a bit.
Looks like I've got some cold weather idle tuning to do.  Any thoughts?

Here's my thinking.  With the MAT sensor located under the plenum, it's
coupling all the heat from the motor.  The MAT readings from a cold to a
warm day only differ by about 6-10 degF, even though outside air temp is 30+
degrees below normal.  Would relocating the sensor away from the motor help?
(Thought about mounting it to the air filter can, right fender well in TPI
Firebird.)  Or, can the air really warm-up that quick when it enters the
plenum?  In that case, is the problem the MAF sensor is giving an erroneous
reading from the cold air?

Any suggestions are definitely welcomed!!!
Steve
