Yep its thats screw..
If its in all the way iac has been defeated
If its out more than 3 turn look further
I have had some that do run A bit fast but try that iac screw if defeated just adjust stop linkage for good idle i can say this bc i live in Hawaii and will not have to adjust for cold hot etc ideally throttle plate should be fully closed pulling air only from the iac bypass at idle hence the screw ECU contols you gas flow after that using the maf sensor water temp o2 and a whole lot of othrr stuff

i asked this question about this screw 2 days ago,,,,that black screw with the spring is for idle as well ,,it controls the idle so when the A/C is on and for Your POWER STEERING ,,,so when there extra strain on the motor..
