Adjusting idle with the screw

Adjusting idle with the screw
I need to bring my idle down about 100 RPM's, is it ok to try and use the screw in the T/B for this or do I need to have a tuner go in and do it through the computer?
It idles at around 900 and I just want to lower it like 50, maybe 100 RPM's to tame it down some.
Thanks

i think idle would be controlled thru the IAC motor only way to change it would be thru like hp tuners or something similar the screw is like a throttle stop with minimal adjustment

If you want to adjust your idle, you will need to have tuning software such as HP Tuners or LS1Edit.

Turning the screw without tuning will cause problems. All of your airflow tables will then be off. Like stated above, it's an airflow adjustment, not an idle adjust screw. Don't do it.

I better go out and tell my engine that because it doesn't know. Raised my idle by adjusting the screw, got a code for unexpected high idle, cleared it went out did the procedure with the tps and haven't had a code or pending code. Idle stayed where I placed it.

If that was the case it would still throw a code, by unplugging it and having the pcm recognize it's not receiving a signal it throws a code. Plugging it back in causes the pcm to calibrate for the "new" sensor.
