Idle speed keeps dropping
A few weeks ago, my idle speed dropped to about 450 rpm, so I adjusted it while simultaneously wondering what might cause such a thing. A few days later, it was back to 450, so I adjusted it again. A few days later, it was back to 450. . . my idle adjustment screw is so far out now, I don't dare turn it any further. I know this is probably a simple fix, but I have no idea where to start apart from checking vacuum lines and obvious things. I didn't see anything, but I also didn't go digging very deep. Is there a sensor I should check? Should I use a hammer? Do I just get used to it stalling at red lights?
