I had the same experience and after cleaning my throttle body the ECU quickly relearned and reset. Seems a dirty throttle body over time will cause the TPS to gradually adjust for that condition. New battery equals reset on ECU and creates the stall problem.

Well, due to a pending trip on Thursday, I need it to work. I'm going to have them replace the part and then cross my fingers you guys are right and all I need to do is drive...
Thanks for the responses.

I also had this problem when cleaning the MAFS and TB. I just had to press the gas pedal down while starting and then it relearned.

I ended up having to replace my entire throttle body (my mechanic used one out of an older Tundra race truck) so I was lucky to find a used one. Hopefully it will last...
I had this exact experience (posted about it) when I removed my battery.
I started er up, and it was idling poorly so I stepped on the pedal for a while to keep the revs at 1k. Afterwards, until I reset the ECU again (DC the battery), I'd stall out constantly.
I've read other reports of ECU re-learning idle across other vehicles.
The problem is putting the pedal to the floor artificially keeping revs high IMO after a battery disconnect.
