I think that only works if you're buying the paint from the dealership... the below is if you're buying from an automotive paint company
I.E. when I went to CarQuest for my paint... the code looked similar to the above.

The duplicolor perfect match uses the factory paint codes. Due to hail I got to replace a cowl on mine and I got to repaint it too. I have already received comments about how it looks just like the factory paint.
Finishmasters, the paint supply company here used the PEA paint code and mixed me rattle cans for my '99. Color matched perfectly.(Chili Pepper Red)

It sounds to me like that TPS is junk.
OBD-II works by establishing a min and max threshold for signal levels. (0V would indicate a closed circuit, 5V indicates a short.) If I remember correctly, at rest (full close), the TPS should read 17%. Anything above the PCM assumes the throttle is being opened and won't mess around with the IAC and will start adding some fuel.
Before writing the TPS off completely, take it off and test the connector going into it. Record the voltage on the +5V pin and measure resistance to the battery negative post from the Sensor Ground pin.

500 ohms is WAY too high. Should be like 3.
