The temp has recently drop to around -21 degrees. I own a 2007 Ford Focus SES. When i start up the car, the RPM's race to nearly max. When driving it feels like the throttle is stuck, the rpms are not steady. As the vehicle warms up abit, the rpms drop abit, when i come to a stop, the rpms will race to around 5000 then 10 seconds later it will drop to normal.

The vehicles computer will adjust the idle according to how the manufacture programmed it
After about one mine or so, the idle on most vehicles comes down to approx 750RPM, generically speaking
When you put the car in gear,assuming it is an automatic, the rpm will drop a 100 at most & may be adjusted by the computer, just as it does when you put the A/C on. That is to compensate for the change in engine load
You should be waiting for the rpm to come down to 650 to 800 & then a couple more minutes for some temp to come up, before driving off. In cold weather wait at least 5 min or more
I think your vehicle is not working correctly, or you not explaining it in a way I understand what answer you want
you may have a vacuum leak, or a bad idle air control valve, the first thing to do is have the computer scaned for codes,you can go to an autozone parts store they scan for free,if there are no codes then look for a vacuum leak around the intake may have a bad vacuum hose.
It does not have a heater motor. The temp control door is controlled by cables located on the driver's side near the gas pedal. If you are talking about the blower motor it is located on the passenger side behind the glove box.
Two ways to help with your problem....You can get a section of aluminum or tin and fashion a heat shield to cover the area that is making the floor hot. when attaching it, use spacers so it stands away from the attachment points. You can also buy heat wrap and heat "blankets" form many race suppliers (I know for sure they are available from Summit racing). Wrap goes on pipes etc and blanket can be installed under your rug. I know it's annoying to have to fix a poor factory design, but at least there is a cure. Good luck!!
It sounds very much like the idle air valve is faulty as I have just had same sort of problem I fitted a new idle air valve and it has cured mine. Unfortunately these idle air valves are not cheap. They are about £70 from ford but you can get them on ebay for about £30 from partsdome
