Recently installed IAV and TPS along with 02 and map sensor. Oil change change and tune up. Vehicle ran fine for a day and then again today as it had previously the RPMs dog down like the vehicle is going to stall out. I heard that after the TPS and the IAV are installed they have to be taken to dealership to be adjusted. Why and what happens if this is not taken in to be adjusted? Or how do I know if these are ok as is and with my ignition or idle timing have to be adjusted?

Does the idle rev up and down? Has the check engine light come on?
