On mornings that are around freezing or below, when I start my truck it idles at around 1200rpms then after about 10 seconds begins to miss and at times, left unchecked will quit. If I immediately press the gas and keep the RPMs above 1200, then it runs without missing and if I drive it, it is ok. However if i do not let the truck warm up before I begin to drive, when I stop at stoplights and such even after the engine is warm it hesitates and misses. However if I let the engine warm up before I drive, or go slow enough for the engine compartment to warm up and then stop at a stoplight, all is fine.
What could it possibly be?

I, too, have this same problem with my car. All the fuses are fine, and the bulbs are fine. The brake light in the back window works, but the read ones do not. This is crazy.

I have experienced this problem on similar vehicles. You should try and replace the coolant temp sensor. If it is not reading the correct temp to the ecm, it will not get the right fuel map. Also, the cts will not always throw a code.
SOURCE: same car/same problem/any solutions/suggestions yet?
it could very well be the fuel filter if this hasnt been changed recently may be a good place to start, also the have platinum spark plugs as imports and prefer to run on 95 or higher octane fuel.. hope this helps

If you haven't already you should check your spark plugs to see if you a bad plug or possibly a bad coil pack.

Typically the brake switch is way up at the top of the pedal assy. (not easy to get to sometimes) The fuse should be listed as a particular # in your owners manual
