There's some kind of pressure switch for the power steering that you may want to have checked.

I personally don't think it's your cold air intake. I was uneasy about leaving mine on all winter and thus far it has not caused any issues for me. I even drove in bitter cold with blowing snow and saw no ill effects.

I definitately am not experiencing any problems related to heat-soak...lol.

I have the same situation as you Worm... At this point I believe it to be the intake manifold. I am putting on the stock airbox, and will take into the dealer next week...****ty.

Haven't had any problems like this with my air-intake and it being -15 here at night and (Brrrr) +10 during the day.
Sounds like it might be an idle problem because at a full turn the RPMs will drop and stall you out.

I just had the same problem a few days ago. My 2000 VX would run rough and stall when I was backing out of a parking spot. It was very difficult to get it started again.

What I had noticed before this happened:

Poor gas milage
shifting problems, up shifted too early under load
hard starting

Solution:
I brought my VX to the dealership and talked to the mechanic, he said he knew exactly what was wrong, a bad seal in the vaccume chamber. He replaced it (under engine/power train warranty) and voila! My vx now runs just fine! No stalls and easy to start. The milage is back to normal (still bad, but better than 10 mpg!)

Bluegrass, your issue is completely different and unrelated to the problem listed. Yours is the known issue of cracked/leaking intake gaskets.
