The little screw by the spring? Yeah several times. I have read that that screw is pretty irrelevant considering the computer does all the adjustments. Also moved the TPS as that is an option with this TB and that did nothing. I’ve read that if I unplug my IAC and it fixes the idle problem that it means I have too much voltage to the TPS but idk how that helps me fix the issue.Have you adjusted the throttle stop on the TB?
