Maybe something with the MAF or IAC? I just guessing, but its possible...

simple thing! IDLE AIR CONTROL MOTOR AND YOU SHOULD
REPLACE THE THROTTLE POSITION SENSOR AS WELL

TPS replaced a week and a half ago. Any idea how much the IAC would/should cost to replace?

This could be key,

Today, I drove my usual 4 miles to work (but I stopped on the way to buy stamps). I get back in the car to finish the ride to work, stalling routine all over again. Same story.

Before you spend any more $$ fill up with 87 octane (yes I said 87). If you have been using higher then that, let your tank get low before refueling. Then, with a tank of 87, take a good long hwy drive (20 miles should do it). If you still have the problem, then start trouble shooting.

A four mile daily drive is not long enough to heat the engine and keep the valves and pistons clean. The cold engine deposits will cause just the trouble you describe. Using gas higher then 87 will also foul an engine. Put them both together and forget it.

Reset the computer by unplugging the battery for 30min.

Ever have the pre-cats replaced under the recall? Constipation of the tailpipe will make it run stupid. Hook up a vacuum gauge to the intake and take a reading at idle. Crack the throttle wide open and slam it shut. If the vacuum takes its time coming up to normal the exhaust system is clogged. Usually when the ignition is screwed up it will miss and/or have low power.
