Idle RPM is usually controlled with the ECU.

This is the case as long as you have the ability to flash. Otherwise the screw you're looking for is on the throtle body, not the IM. When you're looking at the TB from above it's a slightly recessed circle, about half an inch in diameter that takes a flat head bit.
