Help Engine Failsafe after coolant transfer pipe replacement

[Rockit]

I don't want to jamb you up or confuse this. If the car was running fine and now the idle is hunting up and down it sounds like a vacuum leak. Check the main large vacuum lines. Did you replace the EGR valve on the back of the intake when you had it off? if not that could be bad now.

Make sure the mass air flow meter is plugged in all the way and nothing is wrong there.

You will get codes because it's not running right but that might not point out a vacuum leak.

I kept think possibly mass airflow as well. I did not replace the EGR. I will go back and check vacuum lines.

The car was running just fine before I did this. I cleaned the throttle body and stuff when I had it off

I got codes P0120, P0123, P0222. Looks Like I messed up the TPS
