Help! no idle..
For the last couple days my maxima has been having a whole lot of trouble idling.. which could easily have something to do with the fact that it was around -20* this morning, but it just cant seem to keep running without me giving it some gas for the first 5 minutes or so... and that really made stop and go traffic a bitch today on my way home. is there anything here anyone has experienced or could suggest a fix for? oh.. and i replaced my maf a couple months ago so its not that 
thanks
thanks

well its hard to tell becuase it doesnt normally do that when warmer and it is exceptionally cold right now. no cel, except for when it goes on after the engine dies (which i assume happens naturally with a stall because it turns off right away)... it seems like it should be warm enough to run.. and it seems like it should be warm by the time it dies... for comparison, i started up my old '89 camry and that one didnt die on the idle after sitting next to the max in the driveway, so i figured if that car could do it my 2000 maxima shouldnt have a problem..
..that and i couldnt keep it going in traffic coming up on a 4 way stop about half a block from where i was parked, so for a good 10 minutes after the intial start it was dying or struggling to keep running when i didnt give it gas. hmmm.. i guess i rambled a bit. does that explain it better?

my car has been idling funny too when its warming up. its smooth but very rough (best comparison - old muscle car with cams with high lift and long duration)...i can feel it in the floor board and steering wheel. im pretty sure its just the cold weather because its fine when it warms up and its driving fine.

i "preflight" my car. turn car on...heater, seat warmer, and steering wheel warmer on.
go back inside to fill up my travel mug with coffee
get back in the car and drive

sooner, i know what you mean. thats usually what i do too, but when the car cant hold the idle i cant go inside because before i can even get back into the house the engine dies, so it cant warm up unless i'm babying it for a good 3 minutes at the very least. does this show any specific part malfunction besides the air temp sensor as kenshi said?

Have you tried building a fire pit under your parking spot? JK Haha
No... that sucks about the idle... but I did a search and came up with this:
Thought I'd mention it... Hope it helps... GL
No... that sucks about the idle... but I did a search and came up with this:
HFM=Hot Film Mass Sensor=Air Flow Meter
Check every hose connection between the HFM and the cylinder head. The ECU bases its computations on the air flow as measured by the HFM. Any unmetered air downstream from the HFM throws off the computations.
