Don't think a TPS would cause of misfire anyway, a hesitation or stall yes but no misfire. When the light is blinking the PCM is detecting a misfire. At what RPM range does it blink?

You've got a TPS code now...check circuit for voltage, ground, etc. before condemning the TPS. Check circuit as well for the upstream O2 sensor as well. Good luck and keep us posted.
