First of all, a code does not necessarily identify a bad part just a failed system. You need to check the voltage at idle on the tps. It should be.5 to.75 volts. Adjust as necessary.
As far as the low power, you need to start from scratch with a compression test, timing, fuel pressure and check the cat for restriction. One or more than one could be the issue but all needs to be checked and verified.
