Cold Start Rpm in cold temp Options

[Oreo20]

Lately it's been 32° degrees in the mornings
In these kind of temps what rpms should be ok

I'm getting almost 2k Rpms but lowers to 1.2k after warm

In the summer cold gets me 1.4k but lowers to .9k rpm after warm
Is this normal for me or not please help

wow, see this is why this forum is awesome! Thank you guys for the support of my car, I appreciate it. I have a question I would like to ask you before I buy.

So I called the local toyota dealership and they have a water temperature sensor for about $72 for the two pronged sensor. A bit high, so I found this on rockauto, a standard motor products temp sensor for about $17 http://www.rockauto.com/catalog/moreinfo.p...&cc=1317503

Should I also pick up a sender? they are cheap but I don't really have to much funds to be spending. Obviously I will do anything to make my girl run as properly as she can, but you understand my dilemma. Another standard motor product sender for about $15 http://www.rockauto.com/catalog/moreinfo.p...&cc=1317503

Should I just forget about aftermarket and just buy OEM from the dealership?

/edit:

Also the problem could be in the connector/wires to the sensor itself.

You test the sensor with an ohmmeter, when cold it might read 10k-30k ohms, when hot it might be closer to 1k-5k ohms.
If the old connector looks like the wires are about to break off you should repair that. Just go to the salvage yard and clip off one with 4" of wire left on it so you can crimp it to your wires.

Also the throttle opening diaphragm should be set so it idles about 1300 with it all the way out. Disconnect the vacuum line on the diaphragm and adjust the set screw for that.

Really it should idle around 1200 when cold and come down to 800 as soon as it warms up just a bit.

I'm not quite sure how to open the diaphragm. If it has to do with the throttle body, would it better to have someone professionally do it for me? I really like to learn about my car and do things as much as I can on my own, but messing with the throttle opening sounds like I could potentially hurt my car by my own ignorance, however, if there is a tutorial or some type of guide for this I would be more than willing to attempt.
