If they are 'P' codes, off the top of my head it sounds like you didn't hook up the sensors and traction control.
P1120 Throttle Position (TP) Sensor 1 Circuit
P1220 Throttle Position (TP) Sensor 2 Circuit
P1221 Throttle Position (TP) Sensor 1- 2 Correlation
P1516 Throttle Actuator Control (TAC) Module Throttle Actuator Position
Performance
One unhook your battery and take out our PCM fuse leave unpluged for a bit. Plug everything back in then apply your parking brake and let it idle in drive for 5 minutes then in park for 5 minutes. this will help it relearn its Idle.
Also cleen your MAF with some CRC MAF cleener, If you have a K/N filter it will gunk it up.
After that I dont know because the sensors might be diffrent in that TB might have to put your old sensors in your new TB if you can.
