Before you change any more parts. Reset the Idle position with a scan tool with the appropriate software. whenever the position of the throttle plate moves from its average position due to a change in manifold pressure it can set this code. Usually we see this pop up after the throttle body is cleaned or the valves are adjusted. So removing the head could easily set this code. Here is the procedure from the manual.

1. Go to INSPECTION MENU in the HDS, and select ETCS TEST.
2. Select TP POSITION CHECK, and clear the throttle position learned value.
3. Turn off the ignition, then, turn it back on.
4. Reset the ECM/PCM.
5. Do the idle learn procedure.( let car idle for 10 min warmed up with all loads off)
